Peter Allen (born Peter Richard Woolnough; 10 February 1944 – 18 June 1992) was an Australian songwriter and entertainer. His songs were made popular by many recording artists, including Elkie Brooks, Melissa Manchester and Olivia Newton-John, with one, "Arthur's Theme", winning an Academy Award for Best Original Song in 1981. In addition to recording many albums, he enjoyed a cabaret and concert career, including appearing at Radio City Music Hall riding a camel. His song "I Still Call Australia Home", used extensively in advertising campaigns, was added to the National Film and Sound Archive's Sounds of Australia registry in 2013.
Allen was the first husband of Liza Minnelli, with the couple divorcing after seven years of marriage; he later came out as gay. Both he and his long-term partner, Gregory Connell, died from AIDS-related illnesses, with Allen becoming one of the first well-known Australians to die from HIV/AIDS. Several years after his death, the musical The Boy from Oz was written about his life. It ran on Broadway and earned Hugh Jackman a Tony Award for Best Actor in a Musical.
