The Beatles were all young when they were catapulted to worldwide fame, but George Harrison was the youngest, and he didn't always receive the best treatment from John Lennon and Paul McCartney. Lennon and McCartney were writing hit songs right out of the gate, and while Harrison quickly evolved into a great songwriter himself -- penning such classics as "While My Guitar Gently Weeps" and "Something" -- his contributions were never given the same credibility by the band or producer George Martin.
