There seem to be enough songs about Edward IV and his amorous exploits that it looks like he'd become a stereotype Merry Monarch by the 17th century.

I wonder if anybody's made a systematic study of the folklore images of British royalty? There are some with interesting stories that have no songs about them I know of (Wlliam Rufus, or Stephen and Matilda). Are there even any pre-Shakespeare songs that demonize Richard III?
