A message to "learned Nogophilists" in the programme pointed out that there were certain discrepancies between the tale presented on stage and that seen on TV, but explained that this was a function of the frequent reinvention of mythical tales. Graculus was absent, and credit for the flying machine was here given to Olaf the Lofty. In fact, this machine was previously stated to have been invented before the birth of Prince Knut, who was seen as a youth in the stage version. Theatre Programme: Noggin the Nog - The Rings of Nudrug. Birmingham Repertory Theatre. 23 Dec 1971.
