April 15, 2014 marks the one year anniversary of the Boston Marathon bombings that killed three people and injured more than 100.  ESPN commemorated the tragedy with Aerosmith, who recorded a new version of 'Dream On.' 'E:60 Presents Dream On: Stories from Boston's Strongest,'  featured Aerosmith with the Southern California Children's Chorus.

Aerosmith frontman Steven Tyler says the song addresses loss which makes the song sound like it was written for last year's tragedy and not 40 years ago.
