The “mountain” on the cover of John Lennon’s 1973 Mind Games album is the face of his wife, Yoko Ono. Lennon had designed the cover himself. It is seen by many as symbolism for John walking away from Ono’s huge influence on him. The Lennon’s had split up in mid-1973, around the time the recording sessions for Mind Games was to begin. Their separation was to last 18-months before they reconciled.
As a kid, my dad had tapes (cassettes) of The Beatles on for almost every trip in the car; meaning I know the words to nearly every Beatles song in existence! Over the years my favourite song has changed several times. If I had to pick today, I'd go with "In my life". My dad passed away a few years ago, and we had "In my life" played at his funeral, so that's always going to be up there for me.
