A Dave Swarbrick story that he told me -
One of the first times that he was in the studio as a young man was when he had been booked to play as accompanist on a Bert Lloyd album. It must have been First Person (1966). During a break Bert was sitting on a chair and Dave was sitting on the floor by him when he accidently kicked his instrument over.
Bert said, "Don't do that, sonny. It's not good for the fiddle and it's not good for me." - The first words he spoke to him!
