Might have been an honest mistake, it is funny though. I think since Henry has "retired" from music, he's had more time to re-discover bands like Melvins. They never toured together, or really crossed paths back then. Although there was that Melvin Gibbs story where he wanted to join Melvins before Deutrom came on board. Can't remember if he jammed/auditioned or not. I think he'd probably be considered too "jazz-fusion" for Buzz back then.
