40. Carly Simon - You're So Vain

Found on: No Secrets (1972)
Picked by: PA, SB

Carly was pretty clever on this one, making either a denial or admission of guilt incriminating. She also set off a decades-spanning guessing game that still hasn't been given a final answer. If it really is about Mick Jagger, then she deserves even more props for getting him to provide back-up vocals!
