The thing that surprised me most was Lennon's guitar info. He was more specific about what he wanted then I would think.
If you read that site, check out the 57 Les Paul that George had. It has a pretty wild history. From John Sebastian to George Harrison and beyond that. Pretty cool stuff.
As for Paul's Yamaha, I think a lot of their guitars were ones you wouldn't be able to buy in a store.
Speaking of and a little off subject: I went down to Memphis one year and met a woman named Cordell Jackson. She was an old lady who has a really interesting history. She couldn't get a record contract in the 50s so she started her own label (Moon records...the opposite of Sun records) and she produced her own records. She was the one who was in a Bud commercial with Brian Setzer back in the 80s. She passed away last October. Anyway, she was really interesting to talk to and she pulled out a Gibson, I think it was a Les Paul. She said that one day she was talking to the main man at the Gibson factory in Memphis and jokingly asked him when she was going to get a guitar designed for her. She didn't think anything of it until she got a cal from one of the people at Gibson and he asked her what she wanted on her guitar. She mentioned a few things and a while later she was presented with a one of a kind Gibson. I got to play around with it for a bit, but she had a broken string she didn't change out. She was known for her Hagstrom and I did get to play a few tunes on that. Here is a pic of her and I from then with me holding the Hagstrom:

http://en.wikipedia.org/wiki/Cordell_Jackson I just thought I would tell that because of the "rare" guitar stuff I was reading about the Beatles gear. Sorry for the long post.
