Somebody sent me a MIDI of this tune, saying they couldn't identify it. I guess since I am "of an age," I recognized it right away. It's a song I've always liked, and I think Mr. Acker Bilk did a wonderful job of it. I suppose the arrangement of it is a bit like elevator music, but Acker Bilk's clarinet is wonderful.
You can see a YouTube video here (click) and a Wikipedia biograpy of Acker Bilk here (click). He looks pretty young in most pictures you'll find on the Internet, but you'll find more recent photos on his Website (click).
