Funny thing is that I clicked on this just as I was listening to Dvorak's cello concerto, played at the Proms by Slava Rostropovich on August 21 1968 in London, with a Russian orchestra and Russian conductor, on the very day that Russian tanks had rolled into Prague. Dvorák was Czech, of course. There were protests inside and outside the hall and calls for the concert to be scrapped, but it went ahead and Slava played the concerto, and a Bach sarabande as encore, with tears streaming down his face. At the end, he waved Dvorak's score aloft, making it clear that he was on the side of the Czechs. It's a wonderful and passionate performance of one of my very favourite works, and it's all beautifully free on YouTube. So the thing is that not everyone had a spiffin' time in the sixties. The Czech people plus a good few in Vietnam could very likely testify to that.
