I don't know how Frank presented the old Mothers, since I never read the book. There might be some opinions on what he said, but I - or anyone else - could not make any corrections to anything Frank did.
I was hoping for it to be possibly a movie career as I still would like to see that happen. I enjoyed making 200 Motels and did try out for a few things when I lived in LA, but nothing ever happened. I'm still hoping though.
I think that the old Mothers started that trend of rehearsing long hours. We went as long as the later bands did except we didn't get paid for it like they did.
We are not a Zappa cover band. We only play Frank's songs that were recorded by the Mothers of Invention and I think a lot of those songs were complex.
