As a teenager during the 1980s Harte had an epiphany – "Because the moment I lifted a guitar and wrote my first song I knew I was creative", he has said.
The show set records for Irish TV ratings over the period of November 2002 to March 2003 and Harte came out on top, earning the opportunity to represent Ireland at Eurovision Song Contest 2003 in Riga.
In 2003, Harte recorded a cover version of Beyoncé's "Crazy in Love" for Even Better than the Real Thing Vol.
He performed at Croke Park during half-time in the 2012 All-Ireland Senior Football Championship semi-final between Cork and Donegal.
In 2016 he played Louise Ryan & Úna O Boyle's birthday party to a rapt [citation needed] audience of 60 friends and family on a boat on the river Liffey, Dublin.
He also played surprise set for close fans such as Robert Smith in a local Dublin nightclub in late 2016.
