Just a note on this song- I understand that the "rightfu' king" in this case is not Bonnie Prince Charlie, but his father. The words were actually made by a Captain Ogilvie who attended King James in exile and was a private soldier in the French service. He died at the Battle of the Rhine in 1695. Burns was responsible for putting the lyrics and the air together. I'm sorry that do not have the actual documentation of this- I scribbled it on my copy of the song and didn't write down the source. Maybe Miraculous Malcolm can corroborate this info
Best- Julia
