In 1866 the Blue Plaque scheme was founded by the Society of Arts and so this year they celebrate their 150th anniversary. Now managed by English Heritage, London's blue plaques are handmade in Cornwall by the Ashworth family. The first blue plaque was awarded to the poet Lord Byron in 1867, but his house in Holles Street, was demolished in 1889 – today it is the site of John Lewis department store.

The Beatles are the best-selling band in history and – with 17 No1s – hold the record for the group with the most No1 singles in UK chart history.
