Greensleeves is an English song from the late 1500s. Most people in Britain and the United States still know the tune, even if they cannot sing all the words. The song is about a woman in green sleeves, and the feeling is lovesick and a little bitter. Some people like to say King Henry VIII wrote it; that is a famous story, not a settled fact, and you should treat it as something people believe rather than something we know. In the UK the same melody has a second, very ordinary life: travelling ice-cream vans often play it so you hear that the van has come down your street. That use is so common that for many British children the tune means ice cream first, Tudor love song second. It is a title, so it takes a capital G.
