The Rocky Fellers were an American-born Filipino boy band pop/rock band discovered by Stanley Kahn in the 1960s, who signed them to Scepter Records. The group was composed of four Filipino brothers: Tony, Junior, Eddie and Albert Maligmat, and their father, Doroteo "Moro" Maligmat. They had a hit single called "Killer Joe", written by Bert Russell, Phil Medley, and Bob Elgin in 1963. The song was inspired by famed dance instructor and 'King of the Discothèque', Killer Joe Piro. It has many similarities to the chorus of the Mickey and Sylvia hit, "Love Is Strange".
