In 2007 producer Sharon Browne filmed the first ever Celtic Thunder show at the Helix in Dublin, Ireland. The concept was to feature a group of men from Ireland and Scotland, who range in age from 21 to 42, and feature songs that celebrate a common Celtic heritage.  

The resulting show included an eclectic mix of songs ranging from the traditional to international hits and some original pieces along the way. The current cast of Celtic Thunder is made up of diverse performers, Emmet Cahill, Neil Byrne, Damian McGinty and Ronan Scolard.
