While talking about All Things Must Pass, I just bought a Harrison bootleg, called Acoustic Masterpieces. Very advisable, 'cause there are 15 tracks of All Things Must Pass in acoustic versions on it (great) and a lot of interesting other acoustic Harrison tracks, as for example the 1974 TV show with Paul Simon and other fine stuff.
It's released on Birthda Records, no idea whether you can get it in the States or Britain, I bought it here in Germany. Greetings, Klaus
