That's still why Brits refer to their raincoat as a "Mac"!
1) "PENNY LANE" - BEATLES ("And the banker never wears a MAC, in the pouring rain..")
2) "ANOTHER DAY" - PAUL McCARTNEY ("Dipping in the pocket of her raincoat")
3) "AMERICA" - SIMON & GARFUNKEL ("Toss me a cigarette I think there's one in my raincoat")
