Khrushchev took off his shoes and danced
https://en.wikipedia.org/wiki/Babatunde_Olatunji
Olatunji was known for making an impassioned speech for social justice before performing in front of a live audience. His progressive political beliefs are outlined in The Beat of My Drum: An Autobiography, with a foreword by Joan Baez, (Temple University Press, 2005). He toured the American south with Rev. Martin Luther King Jr. and joined King in the march on Washington.
When he performed before the United Nations General Assembly, Soviet Premier Nikita Khrushchev took off his shoes and danced. Later, he was one of the first outside performers to perform in Prague at Václav Havel's request. On July 21, 1979, he appeared at the Amandla Festival along with Bob Marley, Dick Gregory, Patti LaBelle and Eddie Palmieri, amongst others.
