A personal highlight was probably when we got a No. 1 in the U.K. and when the album went to No. 1 in America. The top four that week was us, Adele, Guns N' Roses and Bruce Springsteen. It was ridiculous seeing those names there. Being the first band from the U.K. and Ireland to go to America and debut at No. 1 is just unbelievable.
