Rosalita by Bruce Springsteen.
I remember one of my brother's good friends on the beach at Port Elgin wearing a t-shirt with the words: Bruce Springsteen is God.
Update June 5/07: The fact is, there is nothing...nothing at all like seeing Springsteen and the E Street Band perform this song live. Even after 30 years (!) an aura of unrestrained joyousness emanates from the band when they play Rosalita.
