Theory + The Duet + The Beatles

Worked on some of the Barrett book today. Also working on getting songs ready for an acoustic duo I'm in focusing on Beatles songs and songs from that time period. Got an interesting Rolling Stone magazine yesterday focusing on the 100 best guitarists. I don't understand how Lennon and Harrison were included but McCartney wasn't. I could maybe excuse them for only including Harrison, but if you include Lennon, McCartney better be there too.
