John Legend performed along with "The Roots." This took place during the pre-show leading up to the main rally.
In addition to John Legend, there was also Ozzy Osbourne who sang his hit "Crazy Train." Sheryl Crow was a musical guest as was Mavis Staples. Tony Bennett was there and offered a rendition of America the Beautiful, after singing the same song at the World Series earlier this week.
There were plenty of famous faces at the Rally to Restore Sanity. It was a great day, and one that will be remembered for some time.
