Shaun Cassidy, like his older half-brother David Cassidy,  became one of the big teen idols of the 1970s. The son of actors Jack Cassidy and Shirley Jones, he became a favorite pin-up boy of pre-adolescent girls after the release of his first hit single "Morning Girl." In 1977, he landed the co-lead in the popular television mystery series "The Hardy Boys Mysteries" (1977). One of the all-time greats of bubblegum pop Cassidy earned the distinction of having the biggest-selling solo debut in history. (On vinyl at any rate, it is a record that he is likely to hold for a long time.) He made the obligatory attempt at "serious rock" but the one thing harder than obscurity to overcome in gaining acceptance there, is success in bubblegum. After the "Hardy Boys" hit, and the less successful "Breaking Away" ended Shaun decided that he still needed to "pay his dues" as an actor. Appearing in many stage productions in minor roles that a star would not be expected to take, he made his way to Broadway and the London Stage eventually winning the Dramalogue Award as Best Actor for his performance in "Diary Of A Hunger Strike". He seems to have found his place on the other side of the camera.  In 1995, Cassidy reappeared on television as the producer of the critically acclaimed but seldom-watched horror series American Gothic. In 1997, he returned with another series, Roar which chronicles the adventures of the rebel who fought to create a united Ireland in ancient times. He is currently executive producer and writer for USA's "Cover Me."
