 The NSR is one of the few railways to become the subject of a play. In 1966, Peter Cheeseman, artistic director of The Victoria Theatre, Stoke wrote a musical documentary about the NSR called The Knotty. Featured in the play were the voices of several NSR staff who had been interviewed especially for the play. The script with introductory notes by Cheeseman was published in 1970. Sound recordings of the production, The Knotty - a musical documentary, was released on LP by Argo Transacord (ZTR 125) in 1970 and as a digital version in 2014 it was digitised by Transacord Digital.
