John Kay gets my vote. I'm definitely biased.
John Kay (born Joachim Fritz Krauledat, 12 April 1944). Kay was born in Tilsit, East Prussia, Germany (now Sovetsk, Kaliningrad Oblast, Russia).[1] His father Fritz, born 13 June 1913 in Absteinen (Opstainys in Pagėgiai Municipality), near Pleskau[4] was killed a month[5] before Kay was born. In early 1945, his mother fled with him from the advancing Soviet troops during the Evacuation of East Prussia in harsh winter conditions. Their train got stuck near Arnstadt, which was first occupied by Americans, but then became part of the East German Soviet occupation zone. In 1949, they crossed the already fortified border to resettle in Hanover, West Germany (as recounted in his song "Renegade" on the album Steppenwolf 7). Now living in the British occupation zone, the young Joachim, who suffered from eye problems, listened to broadcasts by the British Forces Broadcasting Service, like the Uprising of 1953 in East Germany. He also saw a news reel about the Hungarian Revolution of 1956, shot and smuggled out by László Kovács of later Easy Rider fame. Kay and his family moved to Toronto in 1958. Five years later, they moved to Buffalo, New York.
