He was born in Dublin to Tommy and Mary Knowles. His singing is centered on showband and cabaret tunes. His early career began when he stumbled upon the clarinet and saxophone at the Dublin Music School. As a young man he joined the Johnny Butler Band followed by Earl Gill's Band, the Pacific Showband and then Dermot O'Brien's showband. His decision to go solo at the peak of the cabaret era, opened up his career.
