If you're secretly longing to grab a seat for the American Idols Live! tour this year then you may now have a good excuse to go without being made fun of by your friends: they'll let you tinker around with the new Guitar Hero World Tour system, and then compete during a special "half-time" competition [1] between Idols and fans.

Since Guitar Hero has already made friends with the Idol franchise, enlisting the top two Davids to star in their hilarious Risky Business commercials [2], it's only natural that they would take them on tour as a cool opening band. You'll find Guitar Hero on Tour and Steven Tyler Editions in booths along the tour route, and as for the half-time competition, GH experts will square off with the Idols on stage to be crowned. . . um, Top Shredder, I guess?

On a side note, who was the evil costume designer that put David Cook in that wig?
