John Peter Farnham is a British-born Australian singer. He was a teen pop idol, billed as Johnny Farnham from 1967 to 1979. Farnham subsequently forged a career as an adult contemporary singer. He mostly performed as a solo artist, although he replaced Glenn Shorrock as lead singer of Little River Band from 1982 to 1986. In November 1986, his solo single "You're the Voice" peaked at No. 1 on the Australian singles charts. The associated album, Whispering Jack, held the number-one position for a total of 25 weeks. Both the single and the album had international top-ten chart success, including the album at No. 6 in the United Kingdom and No. 1 in Sweden. Whispering Jack is the third-highest-selling album in Australian history and as of May 2023 remains the highest-selling album in Australia by any Australian artist.
