The song is anonymous in Philotus, 1603. Thomas Campion later composed a tune for it, but there' no evidence that the song is by Campion. See ZN2799 in the broadside ballad index on my website for several 17th century broadside copies (including Bodley Ballads- Rawlinson and Douce collections, Mudcat's Links). An ABC of the tune is B501 on my website. See Simpson's 'The British Broadside Ballad and Its Music', #501 for numerous 17the century copies of song and tune.
