He debuted in 1993 alongside Keith Duffy, Ronan Keating, Shane Lynch, and Stephen Gately as part of Irish pop group Boyzone.

[1][2] He attended Billie Barry Stage School in Dublin[3] and started his life in the public eye at an early age, appearing in television adverts for Mikado biscuits and the Irish Electricity Board, T-Mobile.

[7] Graham gained a reputation as 'the quiet one' in the band, but despite their success he felt Boyzone's pop-styles did not give him a chance to expand his own musical horizons which included rock and folk.

[1] During his break from Boyzone, he trained as an actor in America, and studied Music Technology and Sound Production after his solo career as a singer ended.

He performed the self-penned song "Baby, Nothing's Wrong" on 4 March on RTÉ One, attempting to achieve an eighth victory for Ireland in the competition, but placed second, losing out to Eurovision 1993 winner Niamh Kavanagh.
