Do you mean duo (Darling/Soph)? I was at North Texas in 1988, when Ed Soph was still there, and Jamey Aebersold gave one of his clinics. I have to say, the guy, no matter what people think of him, can play. Ed Soph was on the gig, but for the life of me, I can't remember the bassist. I don't think it was Darling. I think they brought in the bassist from the 1 O'Clock, who, at that time, was a 15 year-old wunderkind. I remember walking back to Bruce Hall thinking Damn, Aebersold's for real.
