Following several praised performances of the song, Nizlopi decided to release "JCB" as the album's second single through FDM Records in June 2005, but it did not make a major commercial impact. Over the next few months, the song began to circulate around the internet, attaining a cult following. Soon after its release, animation company MonkeyHub created and commissioned a music video later the same year, which further propelled the track into the public eye. Near the end of 2005, "JCB" became a contender for the 2005 UK Christmas number-one single and was re-released on 12 December 2005 to coincide with this event. This release received mostly positive reviews from contemporary music critics and peaked at number one on the UK Singles Chart, losing the position on Christmas Day to "That's My Goal" by "X Factor" series two winner Shayne Ward. The song remains Nizlopi's most successful.
