Sean Booth posted an outtake from 2009?
Then he deleted the post so I can't link to where he put it. But I did
download it.
This is kind of atypical in featuring acoustic instruments. I don't even
know how the hell he did the classical guitar -- cutting up a real
performance? At any rate it's interesting and a nice track on its own.
