Alison MacCallum, also written Alison McCallum, is an Australian rock singer from the late 1960s and 1970s. Her two studio albums are Fresh Water and Excuse Me. In March 1972 she issued her most successful charting single, "Superman", which peaked at No. 12 on Go-Set's National Top 40. In August that year MacCallum provided lead vocals for the Labor Party's campaign theme song, "It's Time", for the 1972 election. By the late 1970s, she had concentrated on session work and then "disappeared from public view". According to Australian musicologist, Ian McFarlane, MacCallum was "a soul/blues stylist of considerable flair and passion". In September 2014 Sony released a 2× CD compilation album, The Essential Alison MacCallum.
