Thanks to everyone for sharing your stories and insights. As many have said, it brings back such memories.

Art Thieme and others covered Chicago scene pretty well. I didn't see Jim Post's name mentioned or the consummate side man, Randy Sabien. Last I heard and saw, Randy was living in Eau Claire, WI and still playing.

Someone mentioned Alan Arkin, but did not see a reference to The Baby Sitters.

The saga of Mike Bloomfield. Great guitarist. Up the thread someone mentioned his work with Electric Flag, there was Bloomfield and Cooper Super Sessions, etc. He had a brother who was as good if not a better guitarist then Mike. Don't know what happened to him.
(Old Chicago family, Mike's father was an executive with Beatrice Foods)

Finally, I may have some of this wrong, but here's what I remember. There was an effort to try to franchise a string of national folk clubs/coffee houses in the 60's called Your Father's Mustache. There was one out on Long Island, and others around the country. There was a group or possibly more than one by that same named that played at them. One played on the Johnny Carson Show one night.

Anyway, one of the guys had a dual career as an architect and was part of the design team for the clubs and played numerous string instruments in the band, Jeff Olswang. Jeff is still teaching architecture in Milwaukee. Also still dabbling in stringed music.
