Paul Allen definitely had the funds to buy all of this stuff. It's surprising to me that he didn't have more interest. I used to gig with a local keyboardist from Texas, who was LeAnn Rimes music directory early in her career. He produced an album a few years back and he hired a Seattle guitarist who was in Paul Allen's practice band to lay down the guitar parts. Brent told me that the guitarist (I don't remember his name) was paid $80K a year to be on call to Paul Allen, so that when Paul Allen wanted to jam, he had to be at Paul Allen's house on Mercer Island in short order (not sure how long he had). He might get called on Christmas Eve or have to take a cruise on Paul Allen's 400 foot yacht (which had a built in performance space). Could be hard on the family, but man that's a sweet gig. And it's one of many indicators that Allen had the bucks to buy all of this stuff without breaking a sweat.
I would love to have the lyric sheet for Hey Jude. Or "The Fool" SG. Or Jerry Garcia's The Tiger. I know that the auction is over, but for future reference, I wonder if they take checks?
