As far as I know (and
AMG backs me up on this), there are only four studio albums. "Alliwannado" was indeed one of their B-sides.
I have the collection "Hold Your Horses," a fan-manufactured B-sides collection, on audio cassette. [1] I've tried scanning it into the computer, but I never sorted out how to do that without getting this weird high-pitch hiss on all the tracks.
Ah well. Even more tracks I would willingly pay money for, but, alas, yon record companies won't sell them to me. :(
[1] The improv setup named "Just Like Life" used to consistently make me snicker, because there's a very good Judybats B-side of that title.
