Here's two folk mondegreens.I must say that when I did them I didn't know english very well... 1) Whiskey in the Jar (the Captain Farrell version sung by the Dubliners)...I misheard "come a band of footmen and likewise Captain Farrell" as "come a band of fat men and they looked like Captain Farrell".Thought about a family revenge or something....lol 2)Also sung by the Dubliners "Off to Dublin in the green"; "but the IRA is fighting for the land that the Saxons stole" ( I guess these are the right words...)misheard as "but the IRA is fighting for the land can have sex and all!" That ruined a bit the sense of the song and used to leave me a bit surprised.
