Legendary Child

The lyrics serve as a retrospective of the band's career. Like other songs by Aerosmith, the lyrics make reference to the band's back catalogue. The line "But we traded them toys for other joys" refers to their album Toys in the Attic and their struggles with addiction. It may also refer to the album's title track of the same name. The line "I took a chance at the high school dance never knowing wrong from right" refers to the songs "Walk This Way", one of the band's biggest hits, and "Adam's Apple" respectively. Both songs first appeared on Toys in the Attic.

Nick Bassett of The Re-View referred to "Legendary Child" as "a brilliant single that could only be bettered if the frontman’s trademark falsetto was put to greater use."[8]

The music video for the song was originally shot on May 3, 2012 and was to feature clips of the band with footage from G.I. Joe: Retaliation mixed in. Just before performing the song on the American Idol finale on May 23, 2012, Paramount Pictures announced that G.I. Joe: Retaliation was getting delayed until 2013 so it could be converted to 3D. This resulted in a halt on the release of the music video until a decision could be made about what to do. On June 2, 2012, actress Alexa Vega announced via Twitter that she would be starring in the video and two days later, director Casey Patrick Tebo tweeted that Vega's scenes had just finished filming. Tebo continued to tweet through June that the video was done and the release date was in Sony's hands. Finally, on July 10, 2012, the music video was released via Vevo and YouTube. The video opens with voice actor Ed Weigle doing a tongue-in-cheek retrospective of the group's checkered past.

On October 20, 2012, as part of Pepsi's NFL Anthems project, Aerosmith released a rewritten version of "Legendary Child" titled, "Legendary Child - Patriots Anthem." The lyrics have been reworked as a tribute to the New England Patriots.
