Been awhile since we checked in on Ed Seeman. Here's a post he calls Electric Circus 60's Disco Zappa Music, with the following explanation:

This 60's disco was located just below Andy Warhol's Loft and down the block on St. Marx Place in Greenwich Village from where Zappa was playing for six months at the Garrick Theater. So I used his music from my "Uncle meat" footage to score this completely unedited film shot on one 100ft. roll.

Thanks for all the posts, Ed. Looking forward to many more.
