Wyrd Sisters - Playtext by Stephen Briggs, Terry Pratchett

Terry Pratchett takes Shakespeare's Macbeth and then turns it up 'till the knob comes off. It's all there - a wicked duke and duchess, the ghost of the murdered king, dim soldiers, strolling players, a land in peril. And who stands between the Kingdom and destruction? Three witches. Granny Weatherwax (intolerant, self-opinionated, powerful), Nanny Ogg (down-to-earth, vulgar) and Magrat Garlick (naive, fond of occult jewellery and bunnies).

Stephen Briggs has been involved in amateur dramatics for over 25 years and he assures us that the play can be staged without needing the budget of Industrial Light and Magic. Not only that, but the cast should still be able to be in the pub by 10 o'clock!

Oh, and a world of advice omitted from the play text:
