One of the tunes we regularly perform is Come Out, You Black and Tans, in which the singer is taunting the para-military thugs hired by the British to make the lands of the Irish rebels "...a hell to live in..." during the second half of 1920. If you are interested in a little more background, an excellent summary can be found at The History Learning Site. (Unfortunately, I can't copy the contents here.)

Thanks to Matt Flannery for finding and providing the link.
