www.mikepachelli.com This guy Mike Pachelli has released a series of YouTube videos that dig pretty deep into the guitar playing of Harrison, Lennon, and McCartney. Although The Beatles are often dismissed as mediocre musicians (including by me), the videos give me a greater appreciation for how good they were. The videos are kind of long but if you've never really analyzed the guitar work of The Beatles, they're quite informative. Pachelli has many other videos analyzing specific songs by The Beatles and other musicians. Pachelli’s enthusiasm is kind of contagious.
