On Revolver, the Beatles continued the musical evolution that would reach its apex on Sgt. Pepper’s Lonely Hearts Club Band. Most consider Sgt. Pepper‘s to be the band’s masterpiece, but when asked about his favorite Beatles album, producer George Martin says, “Pepper’s is one of them, but not the favorite. I like Rubber Soul and I love Revolver.”

John Lennon begins wearing ‘granny’ glasses

In preparation for his role in Richard Lester's film How I Won The War, John Lennon was given an army-style haircut and a pair of new glasses to wear.

Lennon's haircut took place in the breakfast room of the bar The Inn On The Heath hotel in Celle, near Hanover, West Germany. The short-back-and-sides, performed by 28-year-old German hairdresser Klaus Baruch, made headlines around the world.

Baruch shaved off Lennon's sideburns, swept back his fringe and greased it down. The cut hair was later burnt to prevent it being sold.

Although the hairstyle proved a temporary measure, the old-fashioned round National Health 'granny' glasses quickly became a trademark of his public image. They became soon fashionable, and he retained the look until the end of his life.

John Lennon flies to Hanover, Germany

Having finished touring and enjoying a break from recording, The Beatles were free to explore solo projects for the first time.

John Lennon accepted an invitation from director Richard Lester to appear in his film How I Won The War and said: There were many reasons for doing it: a) it was Dick Lester and he asked me; b) it was anti-war; and c) I didn't know what to do because The Beatles had stopped touring and I thought if I stopped and thought about it I was going to have a big bum trip for nine months so I tried to avoid the depression of the change of life by leaping into the movie. The thing I remember is that Dick Lester had more fun than I did.

On this day he flew to Hanover, Germany, for the first part of filming. He stayed in the country until 15 September, filming at a NATO tank range in Celle, a town situated just outside Hanover.
