Tomorrow night (Tuesday), BBC4, 11pm, Meet Sammy Davis Jr - original tx: 5 May 1963. A one-off special produced by Dennis Main Wilson. I'm not sure, but I think it's the source of the clip in The A-Z of LE from Lime Grove Day, with Sammy singing 'Maria' from West Side Story accompanied only by a bongo player. The bongo player remains close to the camera throughout, while Sammy gets nearer and further. For years I'd assumed it was inlay or overlay, but someone on Bernie Newnham's excellent Tech Ops site, possibly Bernie himself, mentioned that one of the types of camera crane used at the BBC had a bucket seat at the camera end, so it's possible that the bongo player was physically on the crane. Watch tomorrow and see what you think.
Some great background on the show from the producer here.
