jinx,
You Could Be Her was a pre-TAW song that Supergroup played, which ended up being a TAW song.
(Thinking about it a bit more today, it dawned on me that he may have meant it quite literally.)
But, they played stuff that ended up on Smoking Monkey, as well.
Some of the Other Experiments were taken from The Little Grey Books lecture series that John Hodgman hosted in Brooklyn.
Now that was fun!
