The show often features elaborate musical numbers in different genres, such as electro, heavy metal, funk, and rap. The show has been known for popularising a style called "crimping"; short a cappella songs which are present throughout all three series. Julian Barratt wrote the music within the show, and performs it with Noel Fielding. Fielding also designed many of the show's graphics and artwork.
The show aired on Adult Swim in 2009, beginning with the third series. The episodes had to be edited for time on US television due to the longer runtime allowed by the BBC, however the episodes aired in full, unedited on the Adult Swim website. The show became a part of the network's Brit Block.
