Presenter, Paul Martin, and I at the Albert Dock

My appearance on the popular BBC 2 afternoon auction show Flog It! was broadcast on Wednesday – recorded on the Albert Dock with presenter Paul Martin.

It was shot back in April when the crew spent the day at three separate locations. My main role was setting up and supervising the BBC’s visit. The six minutes of screen time took almost three hours, including setting up the camera and getting the angles right.

Our picture shows Paul and I with the Merseyside Maritime Museum in the background - the chap in the front holds an enormous collapsible reflector which aims to literally put us in the best possible light.

You can watch the full show on the BBC iplayer. It's available until 4.29pm this Wednesday (18 November).

There was a script of sorts but the director stressed this was only meant as a guide – obviously with takes from different angles there had to be continuity. Some wasn’t used, including a close-up of my hand affectionately patting one of the huge cast iron columns.

In between takes, Paul told me that he started out as a professional musician and became involved in Flog It! through his interest in antiques. I shared some memories of the TV shows I watched as a child. They were always live and anything could – and did – go wrong.

I vividly remember two major stars on separate occasions suffering the indignity of their false teeth slipping,  watched by millions of viewers.

I’m a big fan of the Flog It!, when I can see it, and also The Antiques Roadshow on which I appeared recently talking about some 1960s films discovered at Lowlands community centre, West Derby, Liverpool.

I last appeared on Flog It! about five years ago doing a three-minute tour of the Lady Lever Art Gallery with one of the programme’ specialists, Kate Bliss. We did it in our stocking feet because of the echoes from the polished floors.

Flog It! is an in-house BBC production and takes a lot of careful preparation to bring to the screen.

The rest of the National Museums Liverpool footage is scheduled to be screened at 3.45 pm on Monday 30 November, focusing on the stunning new Museum of Liverpool on the city’s waterfront.

The show visits our workshops where some of the museum’s fabulous exhibits are being conserved. Paul interviews land transport curator Sharon Brown in a carriage from the legendary Overhead Railway.

Also featured are the Lion steam locomotive, star of the Ealing comedy classic The Titfield Thunderbolt, and the first Ford Anglia off the assembly line at Ford’s new Halewood factory in 1963.

The feature ends at the Museum of Liverpool where operations manager Martin Hemmings takes Paul on a hard-hat tour of the magnificent building.

Over the past few days you will have seen news reports on the Australian government's apology for its role in the British child migration programme (you can see the PM's apology on the BBC website). The British government is expected to follow suit shortly.

From the late 19th century Britain operated schemes which sent more than 100,000 children to Canada, Australia and other Commonwealth countries. These children did not travel with mothers or fathers but alone, in groups. Taken from poverty and disadvantage it was believed that they would have a better life working in the clean expanses of the British Empire, where they were a source of much-needed labour.

The children's experiences varied. While some were orphaned, many left families behind, and separation from their homeland often led to a lonely, brutal childhood. Some found happiness with new families, while for others it was a disastrous move. They were made to work long hard hours on farms. Some were abused. Many ended up in institutions. Some were told their parents had died, only to discover years later that this wasn't the case.

The repercussions are still being felt. Many former child migrants and their families are still coming to terms with their dislocation. It's been difficult to watch some of the displaced people on news reports; their sorrow and anger is so clear. Their lives were obviously shattered by their experiences.

It's now recognised that the forced removal of children from their homeland was a bad idea, and one which caused more harm than good, hence the Australian government's apology.

Coincidentally we are currently planning an exhibition on this very subject. 'On their own - Britain's child migrants' is being organised in collaboration with the Australian National Maritime Museum. It opens in Sydney in November 2010 then comes to Liverpool in summer 2011 before being toured to other museums around the country. It will focus primarily on the 1860s to 1960s and the children who travelled to Canada and Australia. Along with Glasgow, London and Southampton, Liverpool was one of the main embarkation ports for children so it's fitting that the Maritime Museum will be hosting the exhibition.

We'll be launching a website in spring next year and will be looking for the reminiscences of people affected by the programme. If you were involved we'd be keen to hear from you.

Homesickness is like seasickness – you only feel better once you’ve stopped travelling. I have suffered from both and hope I never experience them again.

Longing for home gnaws away at the soul and is almost impossible to eradicate. I found that it was just as much the loss of my cultural roots as the absence of family and friends.

The logistics of moving huge numbers of emigrants through Liverpool involved everything from supplying cabins to the plates they ate off – it was very big business indeed.

Around nine million people moved abroad through Liverpool between 1830 and 1930 making it probably the greatest emigration port in world history. It was often very emotional for the passengers as they left their old familiar homes behind for new lives in unknown countries.

Many descendants of those emigrants still have strong emotional attachments to Liverpool because it was the last place their families saw before taking the leap into the dark.

However, some did not like their new lives and returned home. There were a number of reasons for this including work and financial issues but often it was simply homesickness.

The new emigration gallery at Merseyside Maritime Museum focuses on many different aspects of this mass migration.

From the tail end of the era there is a fascinating model of the Blaco portable cabin from around 1920-30. They were made by F C Blackwell & Co of Crosby, Liverpool.

Portable cabins were used by shipping companies involved in emigration from the 19th century onwards. The detailed wood and metal demonstration model was used when shipping companies such as Cunard and Canadian Pacific employed Blaco cabins. They could be quickly installed to cater for individual needs of emigrants.

A wooden trunk was used by the Parsons family when they emigrated from Liverpool to the United States in 1906. Oliver Charles Parsons and his wife Sarah Jane were originally from Wakefield, Yorkshire.

After arriving in the USA they lived with their young family in Tennessee, Kentucky and Wyoming before returning to England in 1914.

Oliver died during the flu pandemic of 1918 and Sarah had to raise here five children alone. She kept the wood and metal trunk with its many memories until her death in 1965.

Photographs show Sarah at Bridlington in 1950 (pictured) and her daughter Minnie Chesters in 1954. Minnie was the couple’s eldest child and had emigrated with her parents.

A new Maritime Tale by Stephen Guy appears every Saturday in the Liverpool Echo. A paperback – Mersey Maritime Tales (£3.99) – is available from the museum, newsagents, bookshops or from the Mersey Shop website (£1.50 p&p UK).
