It's in the movie at the 25 min mark, and starts with an unmistakable Tweedy scream. There's gotta be a bootleg out there somewhere. The movie is streaming on Netflix and is definitely worth watching. It's a great story adapted from Denis Johnson's book of short stories, beautifully shot with a killer soundtrack and score with instrumental work by Joe Henry, excellent acting from Billy Crudup and a gorgeous Samantha Morton, plus a pretty funny early-career turn from Jack Black. Watch the movie first, then see if you can dig up Ooby Dooby. I'll keep digging myself.
