I was told when I was a child that I was related to Lupino Lane who did the original Lambeth Walk. I remember being taken backstage and introduced by my grandmother to one of the Lupino family who had been playing Wishy or Washy at an Exeter pantomime in the nineteen forties, but don't know my precise relationship to the family.
Have a look at, www.britishpathe.co.uk. Lots of wonderful footage on a multitude of subjects from the past. If you type, 'Lupino Lane' in to the search box there are a few bits of footage on him, including when he opened the 'Lambeth Walk' pub, mentioned above and sadly no more.
