Remember When Shaun Cassidy Scored His Only No. 1 Hit in 1977?

Shaun Cassidy reached number one in 1977 with “Da Doo Ron Ron”, the only single of his to top the charts. The success marked the high point of his music career, alongside his better-known work as a television and film actor.

Cassidy released five studio albums from 1977 to 1980 and had three hit singles. His debut also included “That’s Rock ’N’ Roll”, which reached the top five; “Hey Deanie” later became his final top-ten hit. “Da Doo Ron Ron” was written by Phil Spector, Jeff Barry and Ellie Greenwich, and had first been recorded by The Crystals in 1963.
