Lynne Randell (born Lynne Randall, 14 December 1949 – 8 June 2007) was an English Australian pop singer. For three years in the mid-1960s, she was Australia's most popular female performer and had hits with "Heart" and "Goin' Out of My Head" in 1966, and "Ciao Baby" in 1967. In 1967, Randell toured the United States with The Monkees and performed on-stage with support act Jimi Hendrix. She wrote for teen magazine, Go-Set, and television programme guide, TV Week. While on the US tour, Randell became addicted to methamphetamine, an addiction which she battled for most of her life.
