I was lucky enough to see Frank Zappa live on five different occasions.
A guy I knew would bring a blow up sex doll to every Zappa show in Cleveland, walk right down the aisle and hand it to Frank on stage.
The last time I saw Frank in Cleveland, when my buddy came down the isle carrying a classic blow up sex doll, Frank stopped the band, turned around, picked up something on a table behind him, and when he turned back around he had a chin strap dildo with the dildo straight up on the top of his head.
My buddy hands Frank the doll, Frank Fkn Zappa takes that blow up doll, inserted the dildo and proceeded to "spin it on his head" as the band played a never heard before and never heard again song called "I think Ill go to Cleveland and spin a blow up sex doll on my head."
The fact that Frank Zappa took the time to write this song and be prepaired with a custom strap on dildo ready for a moment that may or may not happen was priceless entertainment that could never be impromptu repeated again.
