I thought Billy Preston was the 5th Beatle

Billy Preston was the Black Beatle, you see, to distinguish him from other claimants to the title! Apparently John Lennon actually suggested Preston join the band at one point, but the other members vetoed the idea. His work on the Let it Be album remains legendary, and one wonders how history might have transpired differently had Preston indeed joined the band earlier in their career....
