Opening tomorrow, a major exhibition at the London Transport Museum will take an in-depth look at the role transport played in London during World War I – from how London bus drivers took their vehicles to the front lines to the advance of women into the transport workforce for the first time and, of course, how Londoners fared under the deadly aerial attack of the Luftwaffe. Key among the objects on display as part of Goodbye Piccadilly at the Covent Garden site will be ‘Ole’ Bill’ – a 1911 bus on loan from the Imperial War Museum which was requisitioned for the front and, taking its name from Bruce Bairsfather’s popular cartoon character, featured regularly in Armistice Day parades until the 1960s. Other highlights include World War I recruitment posters, a 1914 female bus conductor’s uniform and a newly acquired piece of ‘trench art’ – a decorated Daimler bus steering wheel. Runs until 8th March. Admission charge applies. For more, see www.ltmuseum.co.uk.

The late comedian Tony Hancock was honoured with an English Heritage Blue Plaque at his former home in South Kensington on Monday on what would have been his 90th birthday. Hancock, famous for Hancock’s Half Hour on radio and TV, lived on the fourth floor of a Grade II-listed building at 20 Queen’s Gate Place with his wife Cicely Romanis between 1952 and 1958. It was the longest time he lived at any property in London and coincided with the most creative and successful period of his career with the show first board cast on BBC radio in 1954 and also appearing on TV from 1956 onwards. Hancock died in 1968. For more, see www.english-heritage.org.uk/discover/blue-plaques/.

A foundation stone has reportedly been laid for a Bomber Command Memorial in Green Park. The memorial, which is due to be completed for the Queen’s Jubilee celebrations in 2012, will be constructed of Portland stone and will feature a nine foot tall statue of a bomber command aircrew. Bomber Command lost more than 55,000 airmen during World War II. The foundation stone was laid by the Duke of Gloucester. Supporters of the monument’s construction have included former Bee Gee Robin Gibb, Sir Michael Beetham, Marshal of the RAF, and  The Daily Telegraph newspaper which is running an appeal to help raise funds for the memorial.
