ok, so I'm an NPR-listening lefty. Anyway, I was surprised to find no reference on the web to this classic story that Henry Sheehan told on Airtalk's Filmweek (which I highly recommend) about Oscar-winning composer Bernard Herman:
A director poked his head into the scoring stage where Herman was conducting the score he had written. He opened the door and he heard Herman yelling "I will not have fascism in my violin section!" So the director just closed the door and walked away.
The Filmweek hour on Airtalk airs every Friday from 11:00am-12pm on 89.3 KPCC.
