Bass army > Kanye West
Spinal Tap's "Big Bottom" at Live Earth, complete with about a dozen bass players:
Gotta say, I've never seen anything quite like that.
The highlight for me, however, was probably Kanye West coming out to guest with The Police during "Message in a Bottle" and being completely useless. Awful and hilarious. Oh, and John Mayer was out there too.
The lineup was pretty lame, so I stayed away for the most part. Anything I missed worth checking out?
