Aerosmith's Steven Tyler and Joe Perry have released a reworked version of the band's classic hit 'Dream On' as a fundraiser for charities benefiting the victims of the Boston Marathon bombing in 2013.

Titled 'Dream On (Boston Strong 2014),' the duo's new take on the song features assistance from the Southern California Children's Chorus; as we previously reported, it made its television debut back in April, as part of 'Dream On: Stories from Boston’s Strongest,' an hour-long ESPN program commemorating the attack by telling the stories of five survivors.

"The tragedy that took place during the Boston Marathon was unfathomable, but Boston is incredibly resilient and became even stronger," vowed Tyler in a statement after their performance. "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."

“The heinous act that took place during the Boston Marathon which shook not only the city but the world and touched us all demanded a positive response," added Perry. "Boston Strong was that response and gave an example of our city’s inner strength. 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."

'Dream On (Boston Strong 2014)' is currently available for purchase via iTunes.
