Paul McCartney was the sole Beatle wearing a beard during the recording and filming of the ‘Let It Be’ album and movie. Ironically, he was the only Beatle without a beard on the cover of ‘Abbey Road’, which was recorded the same year as ‘Let It Be’ (1969).
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.
