Australian rock legend Jim Keays has been remembered as always the master and never the apprentice after his death on Friday.

The lead singer of The Masters Apprentices died at the age of 67 after a long battle with cancer.

A spokeswoman says Keays died at 10.30am on Friday from pneumonia arising from complications from multiple myeloma, which he had been fighting for seven years.

The singer had been on life support since Monday.

The ARIA Hall of Famer began his career in the 1960s as lead singer with The Masters Apprentices whose hits included Turn Up Your Radio, Living In A Child's Dream, Elevator Driver, 5-10 Man and It's Because I Love you.
