Via uploader paulineharrisonbird (née, presumably, Butcher):
Cal Schenkel, artist/designer of early Frank Zappa albums, Freak Out, Absolutely Free, We're Only In It for the Money, and others is seen here hanging out with Pauline Butcher, secretary to Frank Zappa and author of Freak Out! My Life with Frank Zappa; Squidget, Gail Zappa's younger brother (not Midget as annotated) and Casey, caretaker to Frank and Gail Zappa. 'Anything' was written and is sung by Ray Collins (from Ruben & the Jets).
Ms. Butcher Bird is the author of the book Freak Out! My Life with Frank Zappa. I expect I'll be getting back to her at some point...
(And yes it's a little past midnight and I'm cheating on the timestamp again. Ran late with that Who post. And here I didn't know what I was going to post about today...)
