This music video is a song against Bishop Gijsen written in 1979, as performed in 1981, by Dutch rock band Disease.
Translated from site nu.nl in the Netherlands:
The diocese of Roermond knew already on February 11 this year that former Bishop Jo Gijsen had abused children when he was chaplain in South Limburg. The diocese covered up this information all the time.
More about this here.
