Ferry Ridderhof and Peter Garnefski, who would later record under the name Hocus Pocus and various other project names. They were producers and band members of Peplab. In 2011 Doop released an E.P. called The Doop eepee produced by Ferry Ridderhof containing the single My Chihuahua. Doop was best known for its eponymous single, which reached No. 1 in the UK. The song was influenced by the Charleston, a 1920s dance, and was most remembered for its lyrics, which consisted entirely of the word "doop" sung over a fast-paced big band sample. In the USA, a remix of the track by legendary house-music artist David Morales was released. Hocus Pocus was best known for its single "Here's Johnny," which reached No. 1 in Australia.
