Weren't the 200 Motels sessions the time when Zappa sued England for their orchestra fucking up his music and then England countersued him for obscene lyrics in his songs?
Either way, this is probably one of my favorite songs from the 2nd incarnation of the Mothers.
Actually, I heard they sued because he paid them reheasal rates because he treated the movie like a rehearsal for a concert at Royal Albert or some other London concert hall. If what I hear was correct, the judge agreed the Zappa was correct but because it was England he lost.
