BIO
Gage appeared as a contestant on the twelfth series of The X Factor and received four "yeses" from the judges during the auditions after performing "See You Again" by Charlie Puth.
In 2017, Gage portrayed the role of ensemble member Hoffman in Jim Steinman's Bat Out of Hell: The Musical and also acted as the alternate for the lead role of Strat before taking over as the lead full-time on 4 September 2018 at the Dominion Theatre when original leading actor Andrew Polec left the production. As part of promotion for the show, Gage and the cast performed "Bat Out of Hell" in front of 30,000 people in Hyde Park as part of The Proms.
Gage played Romeo Montague in the Max Martin jukebox musical & Juliet at the show's world premiere at the Manchester Opera House between 10 September and 12 October 2019 and remained a part of the cast when it transferred to the Shaftesbury Theatre on 20 November. He performed six songs on the official West End cast recording: "It's My Life", "Love Me like You Do", "One More Try", "Can't Feel My Face", "Everybody" and "I Want It That Way". The show was forced to close in March 2020 due to the COVID-19 pandemic and, in the interim, Gage starred as Jason "J.D." Dean in a summer revival of Heathers: The Musical at the Theatre Royal Haymarket alongside Christina Bennington.
Gage returned to the cast of & Juliet when the show reopened in September 2021. In January 2022, he announced that he was leaving the show and played his final performance on 26 March.
On 23 February 2022, it was announced that Gage would portray the lead role of Clyde Barrow in the original West End cast of Bonnie & Clyde, alongside Frances Mayli McCann as Bonnie Parker. Performances began at the Arts Theatre on 9 April 2022 and the show finished it's run on 10 July. During this run, Gage also participated in a one-off script in hand reading of The Pride in order to celebrate 50 years since the UK's first gay pride rally. On 23 October, Gage performed his first solo concerts at The Outernet. Gage subsequently played Fabrizio Naccarelli in a staged concert version of The Light in the Piazza at Alexandra Palace on 27 November.
On 7 November, it was announced that Bonnie & Clyde would be returning to the West End on 4 March 2023, though this time at the Garrick Theatre, with Gage and McCan reprising their roles.
