Max had competed, unsuccessfully, on the television talent show, Opportunity Knocks, shortly before releasing his first album, Live at Treorchy, in 1973. It was a recording of a live performance at Treorchy Rugby Club, with plenty of audience participation. The songs on the album, especially, Hymns and Arias, soon became popular with rugby crowds, and for several years the entertainer appeared regularly on stage, television and radio, recording further hit albums such as We All Had Doctors' Papers.
Boyce's career suffered a downturn in the 1990s, but he continues to perform and tour.
