Peter Allen (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 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 marriage to Liza Minnelli ended in divorce, and culminated his heterosexual guise. He subsequently proclaimed his homosexuality and publicly entered a relationship with Gregory Connell that lasted until Connell's death, 15 years later. 　　Allen was the first husband of Liza Minnelli, with the couple divorcing after seven years of marriage; he later came out as gay. He and his long-term partner, Gregory Connell, died from AIDS-related illnesses eight years apart, with Allen becoming one of the first well-known Australians to die from 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. 　　Allen commenced releasing solo recordings in 1971, but throughout his career achieved greater success through his songs being recorded by others. He scored his biggest success with the song "I Honestly Love You", which he co-wrote with Jeff Barry and which became a major hit in 1974 for Olivia Newton-John. Her single reached number one in the United States and Canada and won two Grammy Awards, for Record of the Year and Best Female Pop VocalPerformance for Newton-John. Allen also co-wrote "Don't Cry Out Loud" with Carole Bayer Sager, popularized by Melissa Manchester in 1978, and "I'd Rather Leave While I'm in Love", also co-written with Bayer Sager and popularized by Rita Coolidge in 1979. One of his signature songs, "I Go to Rio", co-written with Adrienne Anderson, was popularized in America by the group Pablo Cruise. 　　Allen performed on Australian television for many important occasions; in front of Queen Elizabeth II in 1980 at the Sydney Opera House, before Prince Charles and Princess Diana, once in Melbourne and again in Sydney in 1981, at the opening of the Sydney Entertainment Centre in 1983, where he unveiled for the first time his Australian "Flag" shirt, and the 1980 VFL Grand Final in Melbourne. His "Up in One Concert" of 1980 was a big ratings success across the country. When Australia won the America's Cup in 1983, he flew to Perth to sing before an audience of 100,000. In 1988, he opened for Frank Sinatra at Sanctuary Cove, Queensland. In America, he appeared at the 30th anniversary of Disneyland. He returned to recording on Arista with an album entitled Not the Boy Next Door (1983). In 1990, he recorded his final album on RCA Victor, Making Every Moment Count, which featured Melissa Manchester and Harry Connick, Jr. The song "Making Every Moment Count", a duet with Manchester, was co-written by Seth Swirsky, who also produced a number of songs he co-wrote with Allen, including Allen's last-released single, "Tonight You Made My Day".
