No, not with Crombie. Haven was a local guy and as far as I recall it was a solo session.
Barber, of course, was a huge name at one time in the trad craze of the 50s. When I told a woman of a certain age a few years ago that I liked jazz, she said she too had liked jazz when she was young. Who did she like? - Chris Barber, Kenny Ball and Acker Bilk. A mass following at one time - no American equivalent I think of this very British phenomenon. Of course, at the time I was keepin' cool with Ronnie and Tubbs.
