Maximum Prophet noted that one of the most influential and loud rock bands in the history of music is coming back together to perform at Live Earth this summer. Yes, that's right Tap is Back. The article has some good news (a new single is coming) and some bad news... apparently Derek is in rehab for addiction to the Internet. Best wishes to him on his recovery- I'm sure it won't impact the performance... if Spinal Tap is anything, they are a band.
