Isn't that from the Book of Common Prayer? If it is, they likely wouldn't have used it at Crathie, unless the Church of Scotland also uses it. (I don't know much about either church.)
I will put the link to the Scottish service again.
This is the order that is used at Crathie and all CoS morning services.
