Aside from his recording career, Farnham performed on stage with lead roles in Australian productions of Charlie Girl, Pippin and 1992's Jesus Christ Superstar. He starred in his own TV series and specials including It's Magic (With Colleen Hewett) and Bobby Dazzler and as a guest on numerous other popular shows such as Countdown and Hey Hey It's Saturday. Australian rock historian, Ian McFarlane described him as "the most successful solo artist in the history of Australian rock and pop ... Farnham has retained an affable sense of humour and a simple, unpretentious 'everyman' charm which also makes him one of the most respected celebrities in Australian entertainment history."
