It's no mystery Roger Waters' current tour is very political and very anti-Trump.
One local TV station in Cleveland, WKYC featured a story about a group of kids in a local dance academy chosen to perform "Another Brick In The Wall" alongside Waters at Quicken Loans Arena in Cleveland. The story reported that parents were unaware of the politics - and once the news story ran the kids cancelled.
Then, during the concert Roger Waters called out WKYC on-stage by saying "WKYC, I have no idea what your agenda is, and I don’t give a damn."
