Keith Richards can't play guitar? OK, the trouble with saying that is you just lose all credibility you might have gained as a musician. I mean, I don't want to sound harsh, but, how long have youu played guitar? I know you'll now say, like "35 years nonstop, went to Berklee, studied with Pat Metheny", or whatever, yeah, yeah. Keith Richards is incredible, have you ever listened to an interview with him. He has an immense respect for all types of music (something that never goes astray - note point here), and he's got a remarkable ability for demonstrating different styles, what he hears in music, how he plays it... I'm not even a huge Stones fan, but most guitarists couldn't even carry Keith's luggage.
I bet you that Hammitt would have a lot more respect for Keith's guitar skills than you seem too.
Anyway, chill.... (maybe I should take my own point :D )
I'd be happy to be able to play as well as either of them (though I'd prefer to play like Keef) :D
