This song is an exercise in collecting, a bit like The Unfortunate Rake series. There are so many begging songs. Tae the begging I will go, is the only one I know that describes physical attributes, like long hair and nails, and a greasy hat. The Lancashire version mentions fusty coats and black patches, and pretend physical disabilities, like deaf or blind, and affecting crutches. The Irish (sic) version with the chorus too roo rantin' hoy, is supposed to be about King James, who apparently liked to go around among his subjects in the guise of a beggar. Even Tramps and Hawkers is a begging song
Can't help with a set of lyrics, I have Alex Campbell singing on an album, but that#s it.
