Jon Stewart's Rally to Restore Sanity had its share of musical guests on Saturday (Oct. 30), from Sheryl Crow  and Kid Rock  to John Legend  and Wilco 's Jeff Tweedy. But Stewart's own passionate speech about Americans working together got a musical treatment as well, thanks to the Gregory Brothers, the group behind Auto-Tune the News .

The rally drew thousands to Washington, D.C. this weekend, with Stewart and Stephen Colbert serving as ringleaders. Lines from Stewart's speech seemed ripe for the picking: "Sometimes the light at the end of the tunnel / Isn't the promiseland / It's just New Jersey."
Stewart and Colbert created their own musical hilarity with Yusuf Islam (aka Cat Stevens ) and Ozzy Osbourne . No surprise that the two pundits don't agree, and the result of their argument is a combination of "Peace Train" and "Crazy Train."
