The "Mini-Musicals" is a collection of the little animations, Joni's is BYT that's included on the last video tree.
Joni's involvement in "Changes" was as a writer only. Ralna English (Lawrence Welk fans will know her as half of "Guy & Ralna") does a cover of BSN for the soundtrack. I actually bought the album from E-Bay for the track. So those two I know about, but that damn Godard film has me stuck. Still sleepless, Bob NP: Jethro Tull, "We Used To Know"
