@slaw, I'll bet you know Death Can For Cutie got their name from the song of the same title by The Bonzo Dog Doo Dah Band, found on their debut album Gorilla. And that it is they who are performing in the underground scene in Magical Mystery Tour, at the behest of McCartney.
Their first flurry of four albums are fantastic! I have some old friends who saw them live at The Fillmore, but I somehow managed to miss them, damn it. Their live show was quite an extravaganza. I wonder if videos are available?
