I'm pretty sure that ad actually did run for about a day or maybe 2 here in the states. I seem to remember seeing it exactly one time before on TV (after 9pm on SpikeTV I think)... i diffidently remember the girls on their backs playing the guitars and the chick on the drums.
I can see why it was banned, when you put it in context. They probably figured it wasn't a good idea to sell a game rated...what, T for Teen...by using a model in her underwear with large breasts frolicking about.
That being said, I feel like purchasing the game now.
