Ever since music games became popular, the musician trolls have frequented forums and comment threads everywhere. Typically, these trolls are known for comments like "Yeah, I'd rather play a real guitar, thanks." Imagine then, how strange it must be for real musicians to play fake versions of their own songs. Enter Rush performing the Rock Band version of "Tom Sawyer" backstage at the Colbert Report. To make a long story short, they fail at 36% completion. They don't seem to broken up about it though. Fabulous success can give you that kind of confidence, we suppose.
