A Party For Mother Earth

It's actually much, much prettier than it looks in this picture.

From Family Dog to Friends and Relations, 1970-1971

Does anyone know the story of the end of the Family Dog, and the re-emergence of 660 Great Highway as Friends and Relations Hall? I am sure it's out there, but I don't recall seeing it and I know nothing other than what I see in the listings.

I am presently going through some ca. 1970-1971 listings and find first reference to "Friends and Relations Hall" for March 12, 1971 (Big Brother). I had found listings as Family Dog through scattered through December 1970 (not listed at the Chicken).

Anyway, what's the story? I have been surprised to see nothing reported (as far as I have found) in the various music columns in the Bay Area papers.

Edit: Guess I haven't looked that hard. Heh heh.
