Okay so I just realized that there are 5 more facts, so I'm going to do 5 last facts.
71. The Beatles producer, George Martin, once said Lennon was a "completely impractical man."
72. Though many critics believed Lennon could have been a successful film star, Lennon wasn't interested in acting as he considered it an even more confiding lifestyle than that of a Beatle.
73. Yoko and Lennon held a two week-long 'Bed-Ins for Peace' held at Hilton Hotel in Amsterdam and in Montreal's Queen Elizabeth. During their seven day stay at the Queen Elizabeth, "Give Peace a Chance" was born on June 1st. That year's holiday season, billboards in 11 major world cities read "WAR IS OVER! If You Want It - Happy Christmas From John and Yoko."
74. He drank 20-30 cups of tea or coffee daily.
75. The Beatles were the first to feature the "devil horns" rock hand on an album cover.
