I suppose this news will be lost on many younger fishes. At my age you start to realise you're fast approaching the firing line.. :0
I have an ancient, battered and coverless copy of Humph at the Conway, a super live album from 1954. It is so rough that I only rarely play it, but it was my first 'contact' with Humph. I'd love to have met him.
Incidentally, on the above album is a clarinet blues by Wally Fawkes AKA cartoonist Trog. It is the finest single clarinet jazz tune I've heard.. ever.. and I've heard some. I'll dig it out tomorrow and have a listen.
