Thanks for the references.
I have just created a new blog to extend my Battle of the Boyne history and celebration pages. On the sidebar scroll down and you will find a list of links to orange songbooks on line, full view at google books.
Amazing what is available.

Battle of the Boyne Blog

I will be extending the purpose of the blog to included orange music in general.
As far as I know my collection of Unionist orange loyalist songs is the largest on line.

Enjoy
