Sheehan as well as frontman Danny O’Donoghue and drummer Glen Power formed The Script in 2001.

The group is most known for their breakthrough 2008 self-titled project, which features some of their most recognizable songs including "We Cry," "The Man Who Can't Be Moved" and "Breakeven." The latter song peaked at No. 12 on the Billboard Hot 100 chart.

The Script scored a big hit in 2012 when they teamed up with Black Eyed Peas member will.i.am for "Hall of Fame." The song became a Top 30 hit in the U.S. and topped the charts in the U.K. and Ireland.

Since then, the group has continued to release projects, including 2022's acoustic EP Acoustic Sessions 3. The band released a new single called "Dare You to Doubt Me" late last year.
