I have a signed copy of Bobby Few's Let It Rain, which appears to be the only album released on his own label. I found it in the $1.00 bin at a used book store. It appears to be hard to find. There are a few instrumentals, two Disney tunes and a few vocal tunes. I've also found Uri Caine and Ira Sullivan autographed discs at the same store, surprisingly enough.
An album that I treasure for personal reasons is a signed copy of Gene Ludwig's Duff's Blues. I drove to Pittsburgh to see him play at some loud, trendy restaurant. I think my wife and I were the only ones really listening to Ludwig playing a keyboard/saxophone duet set. Despite not being on his organ (it was a basement restaurant, and he had recently been ill), Ludwig played some nice bass lines with his left hand and was in great form (the keyboard was set to a bass setting in the lower register). When I went up to talk to him, he was a really cool guy, and seemed surprised that someone would drive from Cleveland to see him in a less-than-ideal setting.
I wasn't able to make it to see him again, and he died a couple weeks before the gig we were planning on seeing him at (which ended up being canceled due to illness). The cd serves as a memento of my one chance to see a master. I'm still hoping that his album of Cole Porter tunes, which he was shopping around, comes out one of these days.
