hit that year. The novelty song is Crazy Frog's first and most internationally successful single. The cover was produced by Matthias Wagner and Andreas Dohmeyer, the two members of Off-cast Project, and Henning Reith and Reinhard "DJ Voodoo" Raith, two members of the German dance production team Bass Bumpers. Wolfgang Boss and Jamster! arranged the remix, and later marketed it as a ringtone. The song consists of vocals taken from the Crazy Frog recording by Daniel Malmedahl in 1997. It uses mainly the same part of the two-minute original that was used in Jamster's ringtone release. The song also uses the "What's going on?" vocal samples (as well as the instruments) from another 2003 cover of Axel F, by Murphy Brown and Captain Hollywood (dubbed "Axel F 2003" and sometimes "Axel F 2004" also produced by Matthias Wagner and Andreas Dohmeyer). The "ring ting ting" vocal is sampled from "Yo Soy Cubano" by the band "The Chakachas". The Ministry of Sound hired Kaktus Film and Erik Wernquist of TurboForce3D, the original creator of the 3D Crazy Frog, to produce a full-length animated music video to accompany the release of the song. The video, featuring the Crazy Frog character, is set in the future, and centres on his pursuit by a bounty hunter. The bounty hunter receives notification of a $50,000 reward for capturing the frog. There were three edits to the song. The original version of the song can be found at most P2P networks. This song used the "What's going on?" samples twice throughout the song and the "weeee!" sound is heard before the motorbike section of the song. A radio edit was made which had the frog saying "This is the Crazy Frog!" and removed some sounds, and a third edit was made for the Crazy Hits album with the frog saying "I am the Crazy Frog!" Chart performances Released across Europe in May 2005, "Axel F" topped the charts in the United Kingdom, with some of the best weekly sales of the year (out-selling rivals such as Coldplay by four copies to one), and remained at top of the UK Singles Chart for four weeks and becoming Britain's third best-selling single of 2005, outselling and outpeaking the original version. In other European countries the popularity has differed, with the song failing to make the top 20 in Switzerland at first, before gradually climbing to number 1, whilst
