Well, the coveted domain has been snagged. There's some asp zaniness, info from the official page, and a bulletin board to boot.
An Italian fan site (lucky for me, because I happen to know a little Italian. Mamma mia!) It has a few photos and a mp3 of "Party Hat" from Cactuses Come in Flocks (and the "Miracle of Levitation" compilation CD).
A guy named King Yobachi has a little fan page with pictures and a link. (And now his own domain, with a nice group pic: http://www.kingyobachi.com/gif/mxbx_gatorland.gif (and now that this seems to be down, see my backup of the pic)).
Doug Hargrave has a little shrine to Melt-Banana with four error 404 samples.
