Pink Floyd co-founder Roger Waters is embroiled in a controversy in Poland, where his comments that in part blamed the Ukrainian political establishment for Russia's invasion appear to have led to the cancellation of two of his concerts in Krakow.
Waters, the rock musician best known for his work on Pink Floyd's 1979 album, "The Wall," was due to perform in Krakow on April 21 and 22 as part of his solo farewell tour, dubbed "This is not a drill."
