The Script's guitarist Mark Sheehan missed out on part of the band's greatest hits tour before his death at 46.
The band, known for huge hits such as Hall of Fame, Man Who Can't Be Moved and Breakeven, announced that Mark had died today in hospital after a short illness.
Last year, Mark missed out on the band's America leg of their greatest hits tour, and lead singer Danny O' Donoghue, who formed the band with Mark in 2001, said it was down to family commitments.
