I was falling asleep on the couch, with CNN on.
They did a story, and the details I can remember before passing out:
Guitarist Richie Sambora did a concert for Marines at Camp Pendleton near San Diego. He also gave away 10 autographed guitars.
They were accoustic guitars that you can fold up and put in your napsack.
I'm a big rock 'n roll autograph collector, but Bon Jovi is a band I've never liked. I've heard they're all good signers, though.
