• Tim McGraw co-wrote and performed on this along with Def Leppard members Phil Collen, Joe Elliot and Rick Savage. The Country singer put the wheels in motion in 2005 with the help of his longtime tour manager Robert Allen, brother of Def Leppard drummer Rick Allen. The actual collaboration process began a year later when McGraw sat in on their Hollywood Bowl show. McGraw recalled: "We didn't start with any preconceived notions about the song. Each of us brought something different to the table and we drew on each others influence to finish it out. They are simply one of the best rock bands ever and it was a great time working together." (quote from McGraw's website)
• The song was debuted on the Guitar Hero III music video game. Joe Elliott explained why to NME: "Record companies are looking for angles these days because there's no industry left. Nobody's going to play a new Def Leppard song on the radio because we don't fit the format. I can't see (BBC Radio 1 DJ) Chris Moyles playing anything much more than 'Animal,' and (BBC Radio 2 DJ) Chris Evans isn't going to play our new single, so games were deemed the next best thing. The Guitar Hero people said, 'We'd love a new song', so they put it up and off it went."
