Doe Maar was formed in 1978 by Ernst (CCC Inc., S. Piet Dekker, with whom played in The (1975) and The (1977), introduced him to Jan Hendriks and Carel Copier, spring 1978 at the farm of Gé van de Donk, their later sound engineer. Recordings from this meeting exist on which they played, without any rehearsal, all the Dutch-language songs Jansz had written at that time. Copier came up with the idea of the name after hearing the never officially recorded song Doe Maar. When as asked to form the resident band of that year’s Festival of Fools he added five more members to the band: singers Truus de Groot (later Nasmak), Anouk and Wim van (the later tour manager of the band), and clowns Mart de Corte and Jan Bogaerts.
Afterwards the 9-piece line-up was again reduced to four: ErnstBorn: May 24, 1948; keyboards, sax, percussion), Jan Hendriks (Born: September 20, 1949; guitar), Carel Copier (drums) and Piet Dekker (bass).
Piet Dekker turned out to be a songwriter as well. One of his songs appeared in 1979 on a sampler-album (Uitholling Overdwars) made up of new Dutch-language bands. They also released their self-titled debut on Telstar omitting the sampler-track Blozen (Blushing); along with the ska- and reggae-influences in Hé hé, Als de morgen komt (When Morning Comes), Regen (Rain), Je liet me staan (You Left Me), Er verandert nix (Nothing Really Changes), that later permeated their best known stuff, there were also punk, rock ‘n roll and calypso influences on this first album.
