Notes:
This radio appearence was recorded just a few days after Mutations was released. It was one of the first real promo gigs for the album.
This was the earliest known version of "Bottle Of Blues" (likely the first), which sounds cool with a subtle trumpet solo. "Sing It Again" is gorgeous, with lots of harmonica. The songs feel to me to have very slightly different arrangements than would become the norm. Nothing drastic, just nice touches, like the piano riff leading "Jack-ass".
I have a note saying that Beck for some reason used a "makeshift band" for this performance. But I did not note who they were! My copy of this does not have the interview portions either, in case he talks about them there. He does introduce Fred on esraj, the Indian instrument on "Nobody's Fault" (Fred plays on the record too).
