A Newe Northen Dittye of ye Ladye Greene Sleves

Traditional English folk song most commonly known as "Greensleeves".
A broadside ballad by the name "A Newe Northen Dittye of ye Ladye Greene Sleves" was registered by Richard Jones at the London Stationer's Company in September 1580 and William Shakespeare's "The Merry Wives of Windsor" (1597) has a reference to the song by that name.
Registered at The Stationer's Hall (England) in 1580. Despite arguments to the contrary, there is no proof that Henry VIII was the songwriter. Sources credit John Dowland (1562-1626) with the ballad version familiar to most of us.
