The Masters Apprentices (or The Masters to fans) were an Australian rock band fronted by Jim Keays on lead vocals, which originally formed as The Mustangs in 1964 in Adelaide, South Australia, relocated to Melbourne, Victoria in February 1967 and attempted to break into the United Kingdom market from 1970 before disbanding in 1972. Their popular Australian singles are "Undecided", "Living in a Child's Dream", "5:10 Man", "Think About Tomorrow Today", "Turn Up Your Radio" and "Because I Love You". The band launched the career of bass guitarist Glenn Wheatley, who later became a music industry entrepreneur and an artist talent manager for both Little River Band and John Farnham.
