I saw this thread, and I just wanted to post this. I don't know if any of you know
www.sharingthegroove.org but it's a download and trade community that deals with Bit Torrents and FLAC files. I did a search and found this one show from 1968, in San Francisco, soundboard. Not exactly the era being asked about here, but nonetheless, cool. Maybe everyone already has this show, I don't know. I'll post a link to it anyways...

Sounds like a good show, I haven't heard it though.
