Yep, that Flock. Tom Webb was later known as T.S. Henry Webb aka The Barking Spider. He was a real trip. I've jammed with him in the past. The song I remember by them was "Clown" (I think). By the time I crossed paths with him (I did a full gig with him sitting in), he was a gravelly voiced harp player that had seen better days.
Fred Glickstein also went on to try the idea of a Jazz Wedding Orchestra in the late '80s. His claim to fame was the marketing of the home clone kit. "Be beside yourself with joy" "Be the first to be the second on your block"
The guys I knew were actually in a band called Strategic Air Command that had a few remnants out of The Flock, but none of the original members. Archie was the bassist, as I recall, but that's about it. Out of that band came a singer in one of my bands, and a guitarist in another.
Cool, I saw them in Aurora, Illinois sometime in the late Sixties and was thoroughly impressed. I don't suppose there is a fan site, or any of their music floating around the internet.
BTW
http://flockrock.com/ is so slow loading for me, but links to their music on Amazon. They must have gone through a transition after "Can't You See" by adding horns, but I do hear a similarity.
