I got to see a Ted Hughes translation of Oedipus (?? I think) when I visited London. They did it black-box casual clothing style. I don't remember very much about it, except that there was a portion before a ritual when the cast started chanting in Greek and stomping to a special rhythm, akin to the way the play was actually performed in ancient Greece. I wish I could remember more about it; I wish the me of this age could go back and actually enjoy it!
