Questions like this, and things about comparing versions of tunes and so on, are not easy to deal with on mudcat. The management dont like pictures in the text of our posts(and I havent got a computer and scanner so couldnt do it ), Basically, to answer this easily you need to post a few bars of harmonised song tunes and discuss them, so as you can see the sheet music and the text together. So easy in a book, not the natural way of doing things here.
