I missed this when it happened, a few days ago. Chris was a giant of the British Trad Jazz scene. He's probably remembered more in conjunction with his clarinet player Monty Sunshine's hit recording of Sidney Bechet's Petite Fleur. I loved that recording and learned it note for note (cadenza included) as a schoolboy. Sadly, arthritis has robbed me of that thrill.
RIP Chris Barber
