Wasn't the reason that the Beatles broke up due to the clash between Lennon and McCartney about Yoko Ono?

A dealer that I knew, in the early 70's, claimed that his friend was selling Colombian Gold weed to Lennon, who lived in the Dakota on Central Park West, for 100 bucks an ounce - which was almost twice the street price. Anyway, say what you will about Yoko, but she DID NOT stop John from smoking weed.

Shame on YOU, Paul!
