That is fantastic, Mark seems very relaxed, I guess that is because he's in his studio, and how cool is it, to see him surrounded by some of the most famous and expensive guitars ever made!!! any guitar player famous or amature in the world could walk into that room and be in heaven

I liked watching him play the acoustic guitar, when he plays an acoustic you can just see what an acuarte player he is, and it was great watching him play that ragtime improv piece again, there is a video of him in a French studio in the 80's playing it too, i'm amazed he can remember how to play it.
