There's one big difference between the two bands - the live shows. It was never 'Simon and Milo' on stage, it was James McCollum and Jason Levine. When there was a Gorillaz preformance, though, you had CGI Murdok, 2d, Noodle and Russel on stage, with Damon Albarn usually only coming out after the show.
I...wait...what? THE GUITARIST WILL HAVE AN EXPRESSION OF PERMANENT BRAIN DAMAGE AND NEVER OPEN HIS EYES! THE SINGER WILL HAVE NO NECK! NO, NOT BECAUSE HE'S FAT, HIS HEAD WILL JUST KIND OF FLOAT THERE! I LIKE GLUE
