Well, PHJim, I sing songs in dialect. I love dialect, especially Caribbean, so I like to sing "Day-O" (also known as "The Banana Boat Song", "The Banana Loaders' Song", "Day Dah Light" and "Day De Light") in its traditional version, which uses a lot of Jamaican patois. I was singing it last night (it's June 12 here in Australia) and my brother asked me what "Mi come yah fi wuk, mi no come yah fi idle" meant.
(It's Jamaican patois for "I come here to work, not to laze around".)
