I remember seeing a stack of 'em at the Jazz Record Mart some years back, at a big discount. Maybe it's worth a call?
I keep hoping the date will come back in better sound than these quick-and-dirty mastering jobs.
Mike says he's probably on the Beach Boys' "Good Vibrations," but he put down many parts for it and isn't sure which ones were finally used.
He's one of the most sure-footed jazz pianists I've ever heard, and a heck of a nice guy.
Favorite all-out blowing version has to be Basie's "Taxi War Dance." (If you don't think those are "Willow" changes, just give the trombone solo another listen.)
