Sheehan missed The Script's tour of the US last year. The Script frontman Danny O'Donoghue said at the time that Sheehan missed the tour due to family commitments. 

"It’s his story to tell, but yeah, I guess if I could paraphrase, his children needed a father and his wife needed a husband," O'Donoghue told the Sunday World last year. 

Sheehan later rejoined the band for a string of concerts in Belfast, Dublin, and Cork last summer. 

Sheehan helped found The Script along with O'Donoghue and drummer Glen Power in 2001. 

The indie group became an international phenomenon in 2008 with the release of their debut album "The Script" thanks to the popularity of tracks such as "The Man Who Can't Be Moved" and "Breakeven."

The group landed their biggest hit with the release of "Hall of Fame" in 2012, topping both the Irish and UK charts. 

The Script has released six studio albums and embarked on six world tours.
