Sammy Hagar has announced the formation of a new 'supergroup' that he says will rival Led Zeppelin. Here's the line-up:

Sammy Hagar
Joe Satriani
Chad Smith (Red Hot Chili Peppers)
Michael Anthony (Van Halen)

The sheer idiocy of comparing yourself to Led Zeppelin aside, there's no way any band that includes Sammy Hagar can be called a 'supergroup'.
