Allen is in London to promote Def Leppard's new album, Songs from the Sparkle Lounge. The first single, Nine Lives, was initially available exclusively as a download for Guitar Hero III: Legends of Rock. It's the first time a band has chosen to release a single via a videogame, and Allen's here to talk about that too. Read on to find out why he thinks Guitar Hero is great, even though he's never played it, what he reckons of GTA IV, and why that tea won't have any caffeine in it.
