Tim McGraw is a co-writer on Def Leppard's new single, "Nine Lives." He wrote the song with band members Phil Collen, Joe Elliot and Rick Savage for inclusion on the British band's upcoming album, Songs From the Sparkle Lounge. McGraw's tour manager, Robert Allen, is the brother of Def Leppard drummer Rick Allen. McGraw sat in on Def Leppard's Hollywood Bowl show in 2006. "We didn't start with any preconceived notions about the song," McGraw said. "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."
