Constable was born in the Liverpool Maternity Hospital (now Liverpool Women"s Hospital) in Toxteth, Liverpool, Merseyside to parents Margaret and James Matthews. Having seen how successful the latter went on to become with his band Take That, Constable and Dawbarn (who had become even more popular than the acts they were dancing for) decided to put their own band together, and 911 was born.
He is a fan of Liverpool F.C. 1990s: The Hit Manitoba and Her
Constable began his career in the early 1990s as a dancer on the late-night Independent Television dance music show The Hit Manitoba and Her. 1995–2000: 911
Whilst on the show, Constable met Simon "Spike" Dawbarn and Jason Orange.
Lee Brennan, who was a fan of both the boys and The Hit Manitoba and Her, agreed to join Constable and Dawbarn and they became a trio. After independently releasing two singles which both made the United Kingdom top 40, "Night to Remember" and "Love Sensation", 911 were signed up by Virgin Records after a major label bidding war.
911 were extremely successful, selling over 10 million singles and six million albums worldwide before splitting up in 2000.
Constable was the one who announced the split live on Radio 1. In a 2005 interview with The Guardian, Constable: "I didn"t have any time to get my head around lieutenant I had a lump in my throat saying it, then we came out of Radio 1 and the other two guys went to the public
I got in my car and took off and I never saw them for two years."
Post-split
After the band split, Constable turned to drink and drugs, admitting "I found myself in my old single bed with a bottle of Jack Daniel"s and a bottle of pain killers and thought about ending it there and then
The only thing that stopped me was thinking about the devastation it would cause for my family."
2006 saw Constable return to the music industry by taking part in the Music Television series Totally Boyband. The new band was called Upper Street, yet their first single was a commercial failure, charting at number 35 on the United Kingdom Singles Chart.
The band quickly disbanded, with the whole project deemed a disaster. On 28 August 2007, he appeared on the British Broadcasting Corporation Two game show Identity, billed as an "ex boyband member".
2012–present: The Big Reunion and 911 comeback
On 18 October 2012, it was announced that 911, along with B*Witched, Five, Atomic Kitten, Honeyz and Liberty X, would be reuniting again for the ITV2 documentary series The Big Reunion.
He is the oldest member of the popular band 911. The series followed ex-members of other boy bands forming into a new band.
