It's been a while since we've heard any big Guitar Hero III news. The assault of Rock Band and its variety and scope of DLC shoved GHIII out of the limelight for many. Whether this new development is any sort of attempt to bring back the game's popularity or not, we can't help but think that this would do better in Rock Band. Basically, Def Leppard is going to be releasing its new single "Nine Lives" via GHIII before any retail or online release. The song will be available in a three song pack that will be online for download April 24th in the US and May 8th in the UK. The other two songs in the pack include "Rock of Ages" and "Photograph".
