So maybe The Beatles didn't exactly make this song in anticipation of our beloved Amy's eventual 64th birthday, we're dedicating it to her anyway. The Fab Four did get a couple of things wrong, though-- A-Gutt would never be caught knitting sweaters, and those golden locks are here to stay. The truth: when we're all 64, Amy will definitely be the one partying 'til a quarter to three, and her hair will still look killer.
