Well one of my favorite Beatles song is Why My Guitar Gently Weeps. Also this song also Includes Eric Clapton (He was about 17 or 18 at that time) playing the solo stuff. I think the addition of the keyboard will be awesome because if they have a section similar to the way the drums activate overdrive or the rock ending you can mimic what John Lennon did at the concert at Shea Stadium where he played with his elbows or something along those lines. Which would be neat. I wonder if the keyboard is going to be limited to some of the songs in which involve a Piano such as Hey Jude.
