Earlier this week, The Free Thought Project reported that Pink Floyd frontman Roger Waters stopped a concert in Barcelona to warn the crowd about pro-war propaganda that is coming from a group in Syria known as the White Helmets.

In the days since Waters has taken several interviews to further explain his views, the most interesting of which was with a group called the Grayzone Project, where exclusive Emails were featured, showing conversations between Waters’ team and representatives of the White Helmets.

Waters’ first encounter with the White Helmets was actually long before his April 13 concert, back in October 2016 when Saudi-British billionaire Hani Farsi invited him to a lavish fundraiser that he was holding on behalf of the White Helmet affiliated group “The Syria Campaign.”
