Uncle Jacque - I'm sure Dougie does it (and so do I!) in Open 'C' tuning (CGCGCE) capoed at the 4th Fret, which makes it in E? Check out Dougie's Interactive Songbook CD-ROM, it's on there. Come back and hit me if I'm wrong!

Re the small variances in what people believe are the 'proper' words, I've noticed that performers (Dougie included) often sing slightly different words to the ones printed in sleeve notes. Sing whichever you prefer, nobody will mind! :0)
