There is no greater insult than calling the Fabs a boy band

Rockumentary - Paul McCartney

In this very good 1990 MTV Paul McCartney rockumentary the narrator rightly says McCartney has been many things over the last three decades, a hardcore rock and roller, a pure pop star, a trailblazing bassist, and the cutest guy in the worlds most popular band, but above all else from the beginning he's been a world class song writer. The Beatles producer George Martin is also interviewed and he said that soon after he started to work with them in the recording studio, which was late 1962, early 1963,he said they emerged as pretty brilliant and started to really think about song writing in a very serious way and they showed a film segment of The Beatles in the recording studio which looked like early 1964 during the great Hard Day's Night sessions.
