Party Animal from WikiPedia:

Party Animals are a pop-gabber group from The Netherlands. The band was created by producers Jeff Porter, Jeroen Flamman together with vocalists MCs Remsy, Evert van Buschbach, Patrick de Moor, Dennis Adam and Paul Grommé. They became the first act in the Netherlands to have their first three singles go straight to number one.

The Party Animals made their introduction on the video for the single "I Wanna Be A Hippy" by Technohead. The clip featured three gabbers and a hippie. The producers Flamman & Abraxas discovered the four and saw a potential for opening the mainly underground scene of gabber by making the sound more pop oriented and thus introducing the new genre to a mainstream audience.

The first single was "Have You Ever Been Mellow" which was based on Olivia Newton-John's "Have You Never Been Mellow" and the lyrics still contain parts of the original song with "Never" replaced by "Ever". The music is totally different of course. The single was released in September 1995, however it took three months before it became a #1 hit.
