Kees van Kooten and Wim de Bie open the festive part of the opening of Holland Festival 1975 in the Concertgebouw. "What is beautiful?" the cabaret performers ask themselves, and they present their "Positively Simplistic Culture Note" there. Accompanied by the Promenade Orkest (later Omroeporkest), they sing a duet from Georges Bizet's ‘Les pêcheurs de perles’ (The Pearl Fishers). Van Kooten and De Bie close in their convincingly ironic way under the motto: "Find yourself".
