The adaptation became the very first production at the National's Cottesloe Theatre space, running from 4 March to 27 March 1977. It had first opened in Liverpool on 23 November 1976. The first night of the London version featured Robert Anton Wilson, accompanied by Shea, as a naked extra in the witches' sabbat scene. Wilson was delighted with the adaptation, saying: "I was thunderstruck at what a magnificent job they did in capturing the exact tone and mixture of fantasy and reality in the book. I've come to the conclusion that this isn't literature. It's too late in the day for literature. This is magic!"
