Barry Dransfield, fiddler who played on some of the greatest English folk-rock recordings of the early 70s - Morris On, No Roses and the Fiddler's Dream. For my money, one of the best album openings of all time is on Morris On, where he opens playing the calling-on tune solo, then a brief snatch of the following jig, the calling-on again then the whole band kicks in for the jig again -

I'm also fond of his singing of "Cuckoo's Nest" off the same album, my parents had it taped onto a C60 cassette for playing in the car when we were on holiday, which meant said song was first on the second side. They only played it when they thought me and my sister were asleep given the lyrical content, but I think we picked it up in our sleep, they were horrified when we both sang the chorus one time: "Some like a girl who is pretty in the face, some like a girl who is slender in the waist, but give me a girl that will wriggle and will twist, at the bottom of the belly lies the cuckoo's nest"
