Mary in Kentucky - It is quite normal for the same words to be set twice in a hymnal. Usually one set of words is composed with a tune and then some twit comes along and notices that a different song has the same rythmic structure (text-wise) as another song and changes all the words. There's even a metic index in the back of the Anglican hymn books so that you can change the texts around yourself. It sometimes comes in handy when you see words to a hymn that would go really well in a particular service but none of the congregation knows the tune....so you change the tune and use those words. I really hate doing this though. Anyways, there's a long explanation to your question. Good luck on finding processionals by the way! Let us know what you decide.
