Having enjoyed many years of English Folk music...some of which is very traditional. I have noticed that there were a lot of women through the years that only had one breast...."And on her breast he found"" in the Sailors Lament for example...also there seem to have been a profusion of boys and men called "Willy". "It was willy what got drownded in the deep blue sea"....Buzzer's blowin willy lad" etc etc. Can anyone please explain these phenomenoms.
