In 2006, Donner recorded a rap song together with Meester G to explain his point of view on the Dutch soft-drug policy in response to a song by Gerd Leers, Mayor of Maastricht with punk band Heideroosjes, which called for a more progressive policy which would not only regulate the selling of soft drugs, but also legalise their production.
