From https://en.wikipedia.org/wiki/Doop_(song)

“Doop” is a song by Dutch Eurodance group Doop. It was released on 28 February 1994 as the first single from their debut album, Circus Doop (1994). The song consists of a Charleston-based big band number set against a house backing track. “Doop” achieved success in several countries, including the United Kingdom, where it spent three weeks atop the UK Singles Chart. Two main versions (each with its own corresponding radio edit) were issued under the names of two different big bands, with the “Urge 2 Merge radio mix” combining sections of both. In 2005, the song was covered by Looney Tunez vs. Doop.
