Harold Pinter talks here with Charlie Rose about the difference between "natural and social laughter" and the fact that "it's not nice to be dead," which, now, he is, sadly...
...along with Eartha Kitt ("I'm Just An Old-Fashioned Girl").
Forty years ago, Kitt spoke out against the Vietnam War, as noted here by Wikipedia (and let's try to help them out, by the way), and she was "professionally exiled" from this country. Pinter spoke out against the Iraq debacle, criticizing both Dubya and Tony Blair in particular, as noted here.
For these reasons, I think we should take particular notice of the passing of these brave artists (examples to be emulated by us all, including these people).
