I remember when the bicentenary of the French Revolution was being organised I read that efforts to set up a mass troupe of musicians playing traditional instruments, particularly in Brittany, came up against a problem because many of the best players still held to the view of the revolution responsible for waging ferocious war against their community at that time, and wouldn't consider celebrating it. Rather in the same way that efforts to commemorate Oliver Cromwell wouldn't go down too well in some parts of these islands.
