"Herculean" is the first single by The Good, the Bad and the Queen, an alternative rock band fronted by Damon Albarn. Though Albarn later claimed that the band was unnamed, and that "The Good, The Bad & The Queen" was merely the name of band's first album, this single clearly credits the artist as "The Good, The Bad & The Queen", and was released several months in advance of the album. At the time, neither Albarn nor anyone else was claiming the band was unnamed. "Herculean" was first released as the band's debut single on 30 October 2006, following the band's performance at The Roundhouse in Camden on 26 October as part of the BBC's Electric Proms. The single peaked at number 22 in the UK Singles Chart upon release, and was later released as the fifth track on the band's 2007 debut album The Good, the Bad and the Queen. The song was released to the iTunes Store on 9 October 2006, and a stream of the song is available on the band's website. In a Time Out poll of the best songs about London, the song placed at #50. The artwork for the single was created by the band's bassist Paul Simonon.
