According to Wikipedia "It featured samples from the 1960s children's television programme Trumpton. It followed a popular trend at the time of releasing tracks based around children's TV samples - other songs that did this included The Prodigy's "Charly", based on the 'Charley Says' series of public information films from the 1970s, and The Smart E's "Sesame's Treet", which sampled the theme music from Sesame Street. This subgenre was dubbed "Toytown Techno"..."
Interestingly, it seems that this song is now the subject of some controversy, as 'engineer' Jack Smooth claims that he "originally conceived the idea. I invited Urban Hype to record it with me. I co-wrote, produced and mixed this record. This is contrary to what is credited (only an engineer credit). Everyone who was anyone in the genre (Carl Cox, Phantasy, Fabio, Grooverider, etc, etc, etc) knew I was behind it and they were never taken seriously again afterwards. Some people have no shame, self respect or respect for others. I guess that's why their career lasted only 1.5 years - There is a lot to learn from making such an silly error of judgment..."
