Lupino Lane , the man who made ' The Lambeth Walk ' famous, was a comic who once rivalled Chaplin and Keaton. With the advent of the talkies, his small studio folded and all the negatives of over 40 films were destroyed. After years of painstaking research film historian Philip Jenkinson has managed to track down and restore 14 of the original films. Tonight's programme picks out some of the best moments from the lost legacy of Lupino Lane.
