Rush Plays Rock Band Backstage at Colbert

So, when Rush was backstage at The Colbert Report last week, they played "Tom Sawyer" on Rock Band and now there's video of it. I kind of expected it to be a funny demonstration of how unlike playing real instruments Rock Band really is, with these three seasoned pros failing the song about 30 seconds in. But as it turns out, they did pretty well, which is either a testament to Rock Band's accuracy, Rush's gaming skillz or my inability to correctly anticipate the outcome of web videos. (Hint: I thought Dramatic Chipmunk was going to be totally undramatic.)
