LONDON-Brirtish rock legend and Pink Floyd co-founder Roger Waters’ planned concerts in Poland in April have been canceled amid a backlash to the musician’s stance on Russia’s invasion of Ukraine. Live Nation Poland, the concert’s promoter, confirmed the cancellation Saturday but did not specify a reason. The cancellation comes after Waters, 79, published a controversial open letter on his website in early September to Ukrainian first lady Olena Zelenska. In the letter, Waters wrote that he opposed the West sending weapons to Ukraine to aid the embattled country in its war against invading Russia. Waters also accused Ukrainian President Volodymyr Zelensky of doubling back on his 2019 election campaign promises and said, without offering proof, that “the forces of extreme nationalism that had lurked, malevolent, in the shadows, have, since then, ruled the Ukraine.” Waters went on to accuse these “extreme nationalists” of setting Ukraine on a path to war with Russia by crossing a “number of red lines” set out by the Kremlin. On Sunday, Waters denied he had canceled the shows himself. The shows were planned to take place in Krakow as part of the his international tour. In a Facebook statement addressed to the UK’s The Guardian and Poland’s Gazeta Krakowska newspapers, Waters denied he or his management had canceled the Poland shows.

 He pointed the blame instead to Lukasz Wantuch, a Krakow city councilor who wrote his own Facebook post on September 10 opposing Waters’ shows.

“It is true that a town councilor in Krakow, a Mr Łukasz Wantuch has threatened to hold a meeting asking the council to declare me ‘Persona non grata’ because of my public efforts to encourage all involved in the disastrous war in Ukraine, especially the governments of the USA and Russia, to work towards a negotiated peace, rather than escalate matters towards a bitter end that could be nuclear war and the end of all life on this planet,” Waters wrote on Facebook.

“Not withstanding that this chap Łukasz Wantuch seems to know nothing of my history of working, all my life, at some personal cost, in the service of human rights, he, in an article in a local newspaper urged the good people of Krakow not to buy tickets to my show,” Waters added.

He went on to say that if Wantuch “achieves his aim... it will be a sad loss for me” as well as for Krakow residents.
