Terry's debut novel, Becoming Nancy, was published by Transworld in 2012. Described by Suzy Feay in The Independent as "a deliciously camp rites of passage novel", the book was shortlisted for The Polari First Book Prize. In 2013, Terry sold rights to the book to Tony Award winning Broadway director and producer Jerry Mitchell (Kinky Boots, Legally Blonde, Pretty Woman) who set about turning Becoming Nancy into a major new Broadway musical. With music and lyrics by acclaimed writers, Stiles and Drew and book by Elliot Davis, workshops for the show have taken place in both London and New York and continue into 2018. The show is set to open in the U.S in 2019.

 A South London boy, Terry began his recording career in 1990 when he was signed to MCA records with a top ten single around Europe, Calm the Rage, and an acclaimed album, Roma, recorded in New York City. His 1991 #1 club hit, What The Child Needs, went on to become a soul classic.

 As a songwriter and record producer he has since scored hit singles for Dannii Minogue, Geri Halliwell, Kim Wilde, Sheena Easton and S-Club Juniors. Other production credits include Kylie Minogue, Sophie Ellis-Bextor, Girls Aloud, Bananarama, and Atomic Kitten.

As a vocal arranger and coach, Terry has worked on The X Factor (2007-10) The Voice (2016) The Voice Kids (2016-18) All Together Now (2017) Let's Sing & Dance For Comic Relief (2017) The Brits, Children In Need, Eurovison,  and numerous other TV music specials. He's also worked with artists as diverse as Pharell Williams, Jax Jones, Kylie Minogue, The Wanted, Girls Aloud, St  Etienne, Neon Jungle, Westlife, All Saints, The Saturdays and Cheryl Cole. He appeared as a special guest judge alongside Dannii Minogue on the Judges’ Houses section of The X Factor in 2007.

Also in 2007, Terry wrote and produced musical numbers and original songs for stars such as Elaine Paige, Meera Syal and Olivia Coleman for the BBC TV series, Beautiful People, alongside the show’s musical supervisor, Ian Masterson. He was the vocal arranger on the 2007 West End revival of Jonathan Larson’s Rent at The Duke Of York’s Theatre, starring Denise Van Outen and Luke Evans, and along with director William Baker, musical supervisor Steve Anderson and burlesque star Miss Polly Rae, co-created and wrote The Hurly Burly Show, a bold burlesque comedy which enjoyed three West End runs plus tours in South Africa and Australia.

Terry’s first play, Some Girl I Used To Know, a bittersweet one-woman play with music starring Denise Van Outen, completed a successful UK tour early in 2014 followed by a West End run at The Arts Theatre in the summer of that year. In October 2012 Terry took on dual roles as book writer and vocal arranger on Orchid, a musical, burlesque, circus extravaganza that played for four months in the design district of South Miami. He was also both book writer and vocal arranger on Viva La Drag, the fictional, musical tale of an all-male ‘girl group’, which toured major UK theatres between 2013-15.

Terry has collaborated on five best-selling celebrity memoirs and  co-authored YouTuber sensation Oli White's debut novel, Generation Next and the #1 Sunday Times Bestseller sequel, Generation Next: The Takeover. His latest collaboration is with Dr. Stephanie Green on the 2018 memoir, Flight Risk.

He's currently working on a second novel as well as a brand new musical, The Most Beautiful Man In New York, with long time collaborators Ian Masterson and Steve Anderson.
