[4][5] Glenys did release one single in 1973 on the RCA label, "C’est La Vie", with B-side "Captain Como".
"[8] From 1964 to 1966 she regularly performed with the Esquires and, in 1967, joined a vocal trio, the Creations, with her sister Glenys and Michelle Kennedy.
[2][7][9] That group also backed various solo singers including Billy Adams and then Buddy England and toured Australia.
[2][7] By April that year, with Kennedy, she joined a soul-based group, Dice, which were renamed the Laurie Allen Revue.
[4][9] In April 1967, Allen had told Go-Set: "I realized just a three piece group couldn't give me the sound I wanted, so I added two girl vocalists, [Hewett] and [Kennedy], they are an act in themselves and combined to give us a distinctive sound which can't be done by any Australian group.
"[10] As a member of the Laurie Allen Revue, Hewett recorded on three singles; "Beautiful Brown Eyes" (August 1967), "Any Little Bit" (April 1968) and "As Long as I Got You" (June 1968).
[2] Her popularity with viewers resulted in her winning Best Newcomer Female Singer at the Bandstand Awards in December.
[13] She signed with Festival Records and her debut single, which was a cover version of Delaney and Bonnie's track, "Super Star" was released in June 1971.
[16] Her debut self-titled album appeared in October 1972 and provided her next single, "Carry That Weight" – a cover of The Beatles track – which reached No. 29.
[2][19] During the federal election campaign from February to March that year, Hewett provided lead vocals for the Liberal Party's theme song, "We're not Waiting for the World".
[2] From 3 August to 14 September 2006 she played Marion Woolnough, the mother of Peter Allen, in the Australian tour of The Boy From Oz headlined by Hugh Jackman.
[15] She also had a role as Matron "Mama" Morton in the musical Chicago with Caroline O'Connor and Craig McLachlan.
[23] On 31 March and 1 April 1973, Hewett had the role of "The Mother" (Mrs Walker) in the local version of the Who's rock opera Tommy.
[24] The other Australian artists were Daryl Braithwaite (as Tommy), Bobby Bright, Linda George, Jim Keays, Ian Meldrum (as "Uncle Ernie" in Sydney) Doug Parkinson, Wendy Saddington, Broderick Smith, Billy Thorpe and Ross Wilson.
[25] While performing in Pippin, she and her co-star John Farnham (title role) also hosted a TV variety show, It's Magic, moving between the studio during the day and the theatre at night.
[7] From the 1970s to the early 1990s, Hewett also acted in TV dramas: Matlock Police (1973), Homicide (1974–76), The Truckies (1977–78),[2] Carson's Law, Division 4, Young Ramsay (1977), Cop Shop, Prisoner (1984–85) and The Flying Doctors (1991).
[31] Hewett is the great-granddaughter of Edward Rollins, an Australian middleweight boxer who ran away from his native Guyana in the 1860s and first arrived in Australia via Britain in 1881.
