Here's the original choreography for Gimme More that Britney didn't execute properly for the Video Music Awards 2007 in Las Vegas. Okay, it might not be the original but it's an early version of it. Notice how some of the dancer's move are not completed they "just walk" where at the VMAs they don't.
This is the dance that was intended for the VMA's. Britney did some of it, but not all of it. This video was taken from the early rehearsals. as you can tell, the stage was only partially built.
