Every winter WAKY radio played Don't Eat the Yellow Snow on a regular basis. As a kid, I remember thinking of Frank's music as Cosmic Jazz; it was too deep for me.
Several years ago I read America the Beautiful: A Novel, by Moon Unit Zappa. It's obviously somewhat autobiographical of her life growing up with Frank and trying to find her way as an adult living the shadow of a genius. In the documentary she comes off as sounding like her dad only thought about groupies, which is probably for the most part a perk of the job, but I'm guessing like Dweezil she realizes Frank was many things. Dweezil gives us a technical breakdown of some of the songs on both of those albums. Fellow musicians also give their account of working with Frank.
I used to have one of those Frank on the toilet posters long ago, but I have no idea what happened it it.
Frank Zappa played the bicycle on the Steve Allen show in 1963. Steve Allen is really annoying and Frank comes off as Mr. Cool.
