The band was travelling on a freeway in America during a tour with One Republic last year when the bus was involved in a nasty accident.
The rockers were recording in the coach's mobile studio at the time of the smash, and guitarist Mark Sheehan admits they were lucky to have escaped serious injury.
He tells the Daily Mirror newspaper: "The bus crashed one night. We were in the middle of recording in the mobile studio and we were going 55 miles per hour on to the on-ramp of a motorway.
"The bus slammed to a stop and everyone went flying. A few instruments were harmed but everyone was OK. Thankfully we were pretty drunk at the time. The reality hit us next day - that if we had been in bed (in the bus' bunk beds) at the time of the crash, we could have broken our necks."
