VIDEO: Roger Waters Joined By Eddie Vedder On Stage

Roger Waters closed night two of his three-night stand in Chicago with a special guest appearance by Pearl Jam's lead singer, Eddie Vedder. The two played Pink Floyd's 'Comfortably Numb'. 

This isn't the first time the two have jammed together on that song. They joined forces for a performance of 'Comfortably Numb' during the 12-12-12 concert for Hurricane Sandy relief.

Here's how it sounded during their most recent performance together.
