Back in the late 1970s/1980s I knew an admirable Canadian clarinetist/saxophonist named Bob Burns – alas, no longer with us. You'll all have heard him – he played lead clarinet on the Beatles' When I'm 64. He had spent time working with the likes of Benny Goodman and Jack Parnell and lived in England. An extraordinary player but who wasn't really known to the world at large I guess.
An idle google revealed an alto solo on Jazz 625 (a BBC TV jazz programme – yes, you could hear/see jazz on TV in the 1960s) in a slightly strange situation (because it included 4 cellos) with Bill Le Sage's New directions in Jazz unit.

I was pleasantly surprised a year or so ago to also discover a recording made with the Alan Clare trio in 1960 in which he plays soprano. As far as I can remember, I'd never before heard him play soprano but his intonation is spot on. - Bob's solo starts round about 4'25"
