Terence Nelhams Wright was born on 23 June 1940 at 4, East Churchfield Road, Acton, Middlesex (now London), England, son of coach driver Alfred Richard Nelhams and cleaner Ellen May (née Burridge), formerly wife of Cecil G. Wright, from whom she was separated but not divorced. Unmarried at the births of all their children, his parents were married in 1953. Known as Terry Nelhams, he was unaware his name was Terence Nelhams Wright until he applied for a passport and obtained his birth certificate. The third in a family of five children, Nelhams grew up in a council house in a working class area of London, where he attended John Perryn Junior School. He had his first job at 12, delivering and selling newspapers part-time while still at school. His first full-time job was odd-job boy for a silk screen printer.

Faith began his musical career in 1957, while working as a film cutter in London in the hope of becoming an actor, singing with and managing a skiffle group, the Worried Men. The group played in Soho coffee bars after work, and became the resident band at the 2i’s Coffee Bar, where they appeared on the BBC Television live music programme Six-Five Special. The producer, Jack Good, was impressed by the singer and arranged a solo recording contract with HMV under the name Adam Faith.

His debut record “(Got a) Heartsick Feeling” and “Brother Heartache and Sister Tears”, in January 1958, failed to make the charts. Good gave him a part in the stage show of Six-Five Special, along with the John Barry Seven but the show folded after four performances. His second release later that year was a cover of Jerry Lee Lewis’s “High School Confidential”, backed with the Burt Bacharach and Hal David penned “Country Music Holiday”, but this also failed.

Faith’s success on Drumbeat enabled another recording contract, with Parlophone. His next record in 1959, “What Do You Want?”, written by Les Vandyke and produced by Barry and John Burgess, received good reviews in the NME and other papers, as well as being voted a hit on Juke Box Jury. This became his first number one hit in the UK Singles Chart, and his pronunciation of the word ‘baby’ as ‘bay-beh’ became a catchphrase.

Faith made six further albums and 35 singles, with a total of 24 chart entries, of which 11 made the UK Top Ten, including his two No. 1s. Ten of the eleven singles that made the Top Ten actually also made the Top Five. Faith managed to lodge twenty consecutive single releases on the UK Singles Chart, starting with “What Do You Want?” in November 1959 and culminating with “I Love Being in Love With You” in mid-1964; this was quite a feat for a British artist of Faith’s era.

His début album Adam was released on 4 November 1960 to critical acclaim for the inventiveness of Barry’s arrangements and Faith’s own performances. The material ranged from standards such as “Summertime”, “Hit The Road to Dreamland” and “Singin’ in the Rain” to more contemporary songs, such as Doc Pomus and Mort Shuman’s “I’m a Man”, Johnny Worth’s “Fare Thee Well My Pretty Maid”, and Howard Guyton’s “Wonderful Time”.

At the age of 20 and living with his parents, he bought a house close to Hampton Court for £6,000, where he moved with his family from their house in Acton. In December 1960, he became the first pop artist to appear on the TV interview series Face to Face with John Freeman.

While pursuing his musical career, Faith appeared in supporting roles in films such as Beat Girl (1960) and Never Let Go (1960), and television dramas such as the Rediffusion/ITV series No Hiding Place. In 1961, Faith starred in What a Whopper, supported by Sid James, Spike Milligan, Wilfrid Brambell, Carole Lesley and others well known at the time. A comedy about a writer staging a fake sighting of the Loch Ness Monster, it was written by Terry Nation, and had music by John Barry; Faith sang the title song and “The Time Has Come”. He had a bit part role in What a Carve Up! (1961) with Sid James and Kenneth Connor.

In 1962, Faith co-starred opposite Donald Sinden and Anne Baxter in the film Mix Me a Person, playing a working-class youth falsely accused of murder. The thriller was rated X-certificate (the modern equivalent would be a UK 18-certificate) by the British Board of Film Censors.

Faith’s last Top Ten hit in the UK (in October 1963) was “The First Time” (UK No. 5), which was also his first single with his backing group in 1963 and 1964, The Roulettes, acquired to give Faith’s music a harder ‘beat group’ edge more in keeping with the Merseybeat sound at that time sweeping the British charts. His 1974 single “I Survived” made the Top 30 of the “Capital Countdown” on London’s Capital Radio.

Faith’s teen pop became less popular in the mid-1960s in competition with the Beatles. In 1967, he recorded the psychedelic-sounding “Cowman, Milk Your Cow”, which was written by Barry Gibb and Robin Gibb and released as a single in September that same year. The following year, Faith parted company with EMI.

Faith married Jackie Irving in 1967 and they had one daughter, Katya Faith, who became a television producer.

Following Faith’s 1968 departure from his record label EMI, he concentrated on acting, particularly repertory theatre. After a number of small parts, he was given a more substantial role in the play Night Must Fall, playing opposite Dame Sybil Thorndike. In autumn 1969, he took the lead in a touring production of Billy Liar.

Faith starred as the eponymous hero in the early 1970s television series Budgie (LWT/ITV), about an ex-convict. He was the subject of This Is Your Life in 1971 when he was surprised by Eamonn Andrews.

In 1980, he starred with Roger Daltrey in McVicar, and again played a rock band manager in Foxes, starring Jodie Foster as his daughter.

Faith played the role of James Crane in the 1985 TV movie Minder on the Orient Express – part of the Minder franchise. From 1992 to 1994, he appeared in another TV series, Love Hurts, starring with Zoë Wanamaker.

By the 1980s, Faith had become an investor and financial adviser. In 1986, he was hired as a financial journalist by the Daily Mail and its sister paper The Mail on Sunday. Faith and business partner, Paul Killik, were the principal investors behind UK television station Money Channel. When the channel closed in June 2002, Faith was declared bankrupt, owing a reported £32 million. English film director and producer Michael Winner stated that Faith was his investment adviser, leading to significant losses on two different investments.

In 1986, Faith had open heart surgery. In 2003, he became ill after his evening stage performance in the touring production of Love and Marriage at Stoke-on-Trent, and died of a heart attack early the next morning, 8 March 2003, at North Staffordshire Hospital.

In 2002, he appeared in the BBC series The House That Jack Built. In 2003, he appeared in an episode of Murder in Mind.
