Great thread! I thought I'd learn a bunch of their songs, and I have, but not having a 2nd guitar really sucks, unless you're playing finger-style. Lawrence Juber comes to mind. If you've do have not these, Rob Taylor's videos do a great job of breaking the songs down, Beatle to a Tee. The deconstruction videos are the best! Individually, the playing sounds sloppy but when mixed it sounds great. Here is Clapton doing While my Guitar Gently Weeps with his guitar isolated for the most part. Here's McCartney on the bass. Here's both.
