Sheehan passed away on Friday at a hospital following a brief illness, according to the band. The Script referred to him in a statement as a “much loved husband, father, brother, band mate, and friend.”
The Script, a band Sheehan, Danny O’Donoghue, and Glen Power founded in Dublin in 2001, topped the U.K. and Irish charts with their self-titled debut album in 2008. It featured the No. 1 singles in five different nations “We Cry,” “Breakeven,” and “The Man Who Can’t Be Moved.”
The band’s pop-inflected rock sound made it one of Ireland’s biggest bands in the 2010s. The Script went on to have six Top 10 albums in the U.K. and one top three album in the U.S.
Irish President Michael D. Higgins praised the band’s “originality and excellence” and sent condolences to Sheehan’s family.
“Through their music, Mark and The Script have played an outstanding part in continuing and promoting this proud tradition of Irish musical success across the world,” Higgins said.
Sheehan is survived by his wife, Rina Sheehan, and their three children.
