I'm not sure you want to continue going down the lyric track on this one! I'm collecting cover versions, and I've got it by 226 different artists, not including downloads. I don't even want to guess at the lyric differentials; there's probably 50 different! Bozie's and Brother Claude's are still the best, although completely different songs in terms of style. I never have been able to find anything definitive on the authorship. Any information on those who have recorded it would be greatly appreciated.

Thanks!
