What a good idea.
I did notice that none of the people in the four videos I watched were real players. They made some neat music, but that was due to their singing and song writing and not their guitar playing. They mostly used the guitar for strumming and one guy did some arpeggios. I'll admit that I didn't listen all the way through, so some may have showcased the guitar work later on.
I'd like to see the old guitar in the hands of some guitarists rather than singer/songwriters.
