An amazing selection of Beach Boys material that is not commercially available (concerts, sessions, outtakes, alternate mixes, etc.) can be found at http://bootlegz.blogspot.com
The Rapidshare downloads are kind of a pain (ftp accounts can be had for about $5 for 10 gigs, think about it bloggers), but there's alotta great stuff up there. Check it out BB's fans.

One of these had a version of Good Vibrations that was almost twenty minutes long. KCOU had a copy of it when I was in college.
Does anybody know which of these bootlegs has that particular track?

I love the song Surfing U.S.A

It's a 15 minute version and it's on a disc with the code T 2580-2 on the spine. I think that should identify it for you, I found it web browsing a few months ago. I haven't re-researched it today though.
