Steven Tyler and Joe Perry‘s re-recording of the Aerosmith classic “Dream On” — which they did earlier this year for ESPN’s news magazine show E:60 and its feature on the first anniversary of the Boston Marathon bombing — has been released on on iTunes. They were joined for the recording by the Southern California Children’s Chorus, who were their special guests at Wednesday night’s show in Los Angeles during that song.

Tyler says, “The tragedy that took place during the Boston Marathon was unfathomable, but Boston is incredibly resilient and became even stronger. I am so honored to release this version of ‘Dream On’ and to be able to have had the Southern California Children’s Chorus perform with us last night was a beautiful moment, a true gift from up above.” And Perry adds, “I would like to think that the strength of our performance on ‘Dream On’ last night with the Southern California Children’s Chorus in L.A. at the Forum was another rallying point for the goodness in all of us.”
