Shanty, shantey, chantie, chanty, chantey, shantie, whatever. There is more than one way to do it. (do a google on TIMTOWTDI) Somefolks say it's from the frech for "to sing", some say it's from the shanty cabin. However you spell it, I enjoy singin' 'em! The disparate spellings make it hard to look for, I'll grant you!
