this film of Zappa is his first television appearance if I'm not mistaken.
I've probably already written about this in another thread, but I saw Zappa and the Mothers of Invention on a late night talk show in L.A., when they were largely unknown. The show was called The Joe Pine Show, and Pine was an abrasive loudmouth that picked fights with the audience members. Zappa's band was called -- I think -- The Three Cherry Sisters. A hell of a long time ago, 1960s.
