Perhaps 'woman' in the song actually has a name which could be used? Certainly better than 'darling', 'darl', 'sugar', 'honey', etc.

Actually, I must admit to not being much of a Williamson fan. I know his songs are popular, he has sold a squillion gold records and stuff like that, but there are other writers I prefer - probably sacriligeous to say given that we live in Tamworth, but there you go.
