We Shall Overcome, by Toots I think. Good one from last year's set.
I remember an episode of the show "HOT L Baltimore" when the hotel staff wanted to strike, and one woman, who was supposed to be Puerto Rican, I think, thought the words were "We shall come over..." despite the awesomeness of that little joke, I think the show lasted one season.
