was a Pole who sought refuge in the UK when Communism ruined Poland
Man oh man... Poland was really rough to Andzej Panufnik.
First they punished him by giving him the reins of the Warsaw Philharmonic Orchestra - the leading one in the country. Then they decided it is not enough, and made him head of the Polish Union of Composers. Deciding that his liberalism was taking on a dangerous bent, they decided to send him to Moscow to meet Dmitri Shostakovich and Aram Khachutarian. Further, he got to meet the Zhou Enlai the premier of China.
He was so restricted in his movement by the communists, that he went ahead and married an Irish woman, and made regular visits to the British Embassy before finally emigrating.
Truly, the Communists were worse than the Nazis. Good for him for escaping!
