Only know him casually. Played a few gigs with him back in the day. You're right on all counts.
BTW, he was a HUGE indirect influence. Cat also has had a career as a jazz DJ. First heard him in the early '70s on KNOK-FM outta FW, featuring the omnipresent "Have YOU been to Mr. G's Motel?" ad ALL freakin' night. He did the all-night shift M-F, and I'd stay up all night, even on school nights, listening. The station faded in and out quite a bit (I was 130 or so miles away), so it was a hassle, but he played the best of the old and all of the new (good AND bad). Heard a lot of things, GOOD things, for the first time on that show. And some bad things too - he played the SHIT outta BLACK BYRD when it came out...
He later had the afternoon drive-time show on the old KSAX-AM, a dawn-till-dusk all jazz station that was around in the late '70s. He'd play a BUNCH of then OOP BN stuff, long jams back to back to back, stopping only for commercials. Great times, those were. No bullshit, just groove. And in classic AM sound, no less. The kids today don't know what they're missing. Seriously. AM has a MOJO.
Then he went to our now-defunct jazz FM station (can't remember the call letters right now, darn it), and finally was on public access KNON-FM, playing a lot of the same LPs he played on KNOK. I'd hear the scratches and think, "I knew you when!" Guess he finally retired from radio. Too bad.
Yeah, Bob Stewart's cool!
