WOW! Thanks for the link to the Bill Graham vault. Thanks too for the Led Zep info also. If I live long enough, I'll know a thing or two. The other ISB set in the vault is from the Fillmore West (now the location of a Honda dealership) dated May 11, 1970. My wife and I and our future son ( he born Oct. 12,1970) went to see them that night. The room was so full of grass smoke, you'd have to use an aqualung to not get high. Good times. Pete Grant played with them that night (along with Rose, Licky, Michael, Robin). Loads of SF Org staff were there. A very fun evening. The band had done the solo course at ASHO when my wife was the solo course sup.
