Les, Lord Invader was a genuine calypsonian from Trinidad who recorded in the 30's and 40's. Dick Spottswood, a calypso connoisseur who has put together some great calypso compilations for Rounder Records, says that The Lion, The Tiger, Attila the Hun, Lord Executor, Lord Invader, Lord Beginner and King Radio were "power names taken by calypsonians as compensation for their status at the bottom of the social and economic ladder."

If you like calypso, Rounder has out three great collections:
Calypso Pioneers 1912-1937 Rounder 1039
