"A Memorabilia Collection That Rocks"

Oh. My. God. An excerpt:

Graham didn't just save memorabilia from the concerts, he saved the concerts themselves--rare, high quality recordings of legendary concerts that haven't been seen or heard, in some cases, for 40 years.

Just to give you an idea of what Sagan discovered: The Who's last performance of their rock opera, "Tommy," before drummer Keith Moon died at age 26, and the last concert ever from the British punk-rock pioneers The Sex Pistols.

Bill Graham's cameras had captured most of all the big names through three decades of rock. The Allman Brothers, Chicago, Lenard Skynard, Peter Frampton, Bob Marley.

And more concerts were discovered on audio tapes. On the wolfgangsvault web site, fans can now listen to previously unreleased versions of some of their favorite songs.

"It's tough to do your job because it's so tempting to go down and just listen to audio or go look at video," said Sagan about opening up all the boxes. "I could spend all day doing it every day."
