Around 500 people protested against the appearance of the Pink Floyd co-founder on Sunday. Waters has been criticized for his closeness to the Boycott, Divestment and Sanctions (BDS) campaign.
The Berlin police have started investigations against Waters on suspicion of incitement to hatred. Because he knows the history of the Frankfurt Festhalle, he refrains from dressing up "as a demagogue" in the second part of his show, Waters says. He knows that many people accuse him of being an anti-Semite.
