"Underclass Hero" is the first single off of Sum 41's fifth studio album Underclass Hero. It was officially released on May 15, 2007. The song in its entirety was leaked on April 23 from a 91X podcast interview with Deryck Whibley. It was confirmed on Sum 41's official site that this is the opening track for the album. It is now one of the songs on their MySpace page. The song is also available on iTunes and other digital music suppliers as a digital single, both in Canada and The United States. Additionally, the song is featured in the EA Sports game Madden 08. Originally, the song was to be released in a physical format in the UK on the 30th July 2007 on 7" vinyl to promote the release of the new album, but after a week of taking pre-orders on HMV and Ebay, the 7" is no longer available and the release may have been cancelled.
