The vocals for the group's various songs are performed by Bob Fosco, notably in Gabbertje. However, actor Ruben van der Meer sings one of the group's songs,
Gabberlove. The song
Gabbertje, a parody text set to the theme of the 1970s Dutch series
Swiebertje, is released in 1996. The music video accompanying the single's release is directed by Benjamin Landshoff, a friend of Fosco and director of
Erwassus.
Gabbertje reaches number one in the Dutch charts, including the
Dutch Top 40. The single becomes both gold and platinum
certified. A German version of the song, titled
Ratzekahl (German for "
rat skull"), is also recorded, this time featuring Neel van der Elst. Following this success, Hakkûhbar releases other songs such as
Supergabber,
Gabbersaurus, and the double single
Feestbeest/
Gabberlove. The music videos for these songs are directed by
Martin Koolhoven, another acquaintance of Bob Fosko. These singles and some other tracks are compiled into an album titled
Vet heftig, released in 1997. To coincide with the album release, Hakkûhbar produces a short film,
Vet Heftig – de video, chronicling the rise and fall of the group. The film is produced by Martin Koolhoven, with leading roles played by Van der Meer and Fosko, alongside
Marco Borsato, Tatum Dagelet, Tjeerd Oosterhuis, Nance Coolen, Bart Vleming, Harry de Groot, Anita Doth from the Dutch group
2 Unlimited, and Alfred Lagarde. The film is broadcast multiple times on
TMF Nederland under the title
Vet heftig – de film. A DVD was released in 2004, featuring the short film, the album
Vet heftig and all the music videos. == Discography ==
