Runaround Sue

"Runaround Sue" is a rock and roll song (in a modified doo-wop style), originally a US No. 1 Hot 100 hit (No. 4 on the Hot R&B chart) for the singer Dion during 1961, after he split with the Belmonts. It was written by Dion with Ernie Maresca, and tells the story of a disloyal lover.
