Special Version of 'Dream On' Recorded For Boston Marathon Coverage

Aerosmith's Steven Tyler and Joe Perry teamed up with the Southern California Children's Chorus for a special version of "Dream On."

The new version will be featured on an ESPN special in advance of the Boston Marathon. The song will be part of the E:60 series, during a segment entitled "Dream On: Stories on Boston's Strongest," focusing on last year's terrorist attack that killed three and injured over 250.

The Boston Marathon is set for April 21. You can watch coverage on NBC Universal Sports.
