Paul McCartney and Chris Barber
This was taken at the Marquee studios in Wardour Street. Paul McCartney was sitting on a grand piano. It's quite an interesting combination because he's playing with Chris Barber, who is a jazz musician, the one in the striped shirt. They were recording a song for Chris Barber's record and he was there just adding a bit to that recording.

I would say Chris Barber is the actual person who introduced R&B to this country. He was a traditional jazz musician and played with Lonnie Donegan, but he had some of the first R&B people in his band, including Cyril Davies and Alexis Korner who both moved off and started their own bands, quite successfully.
