From the way Paul McCartney holds his bass guitar, it’s pretty obvious that he’s left handed. Less obvious as a left hander is Ringo Starr. Although Ringo is left handed, he plays the drums as a right hander and his drum kit is set up as such. As a side note, this is the opposite of Micky Dolenz of The Monkees who is right handed but plays with the kit set up for a left hander.
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.
