OTT were an Irish boy band of the mid-late 1990s. The five members were Niall O'Neill, Alan Fitzsimons, Alan Mates (known as 'Adam' in the band), Glen Clarke and Keith Cox. They were signed to Sony Music and had a number of chart hits in Ireland^[1] and the UK.^[2]

After three top ten single releases in Ireland, the group attempted to break the UK market minus Keith Cox, who had left for family reasons. Although moderately successful in the UK, scoring four top 30 hits, the group became well known in Asia with sales of up to 250,000 copies of their debut album. After being dropped by Sony in the late 1990s, the band called it a day.

OTT's Alan Fitzsimons competed in the first series of TV talent series The Voice of Ireland,^[3] being eliminated in the semi-finals. Fitzsimons works in the mobile communications industry, O'Neill now runs a multi-media company in Dublin, having worked at a Spanish tourist resort, Mates is an interior designer, and Clarke lives in the United States.^[4][5]
