Stephen Roe has identified this as "The Visit". He has now found the programme and confirmed that the production was 7, 8 and (th March 1974. Paul Corkrum remembers doing the lighting for the production. The programme identifies Paul as responsible for lighting with David Stanley and Ann McCann. In the photo below, the Athlete vaulting the horse is Dave Stewart. Having looked at the programme, Stephen remembers what one of the Athletes, Tommy Vaughan, sustained a minor injury and was replaced by Gerald Henson either after the dress rehearsal or first performance.
Stephen is sending me the programme and other material to add here.
