You will certainly need permission, from the Laird o'the Pipes. Makee a small cross from two rowan twigs, tie to it a sprig of heather and a silver button, and go to the Mains o'Balspindie at midnight on St Andrew's Day. Light the cross (you may need some paraffin and an old rag to help), prop it in the window and knock three times at the Great Gate.
Say loudly(holding your clarsach tightly with your left hand)
"Double double Hodden and Flodden,
I want to play my braw mickle pipes on the Field of Culloden".
You should be all right then.
