I bought my mum two tickets for the play. She went last night, with a friend, and both said it was great. Even the local newspaper gave it a good review, although they criticized the speed of the scene changes (apparently there are a lot of them). However, they did point out that they saw the play during the first week of a national tour and the scene shifters should soon get the hang of what sounds to be a complicated job once they have got some experience under their belts.
From what my mum and her friend say, Dirk Bennedict played the part very well, with a lot of humour, and that the play is well worth seeing!
