Dude 1981 I'm afraid my carer and I are at a loss with your request. Though it would be helpful to put a link with the title. Any help you can provide would be most appreciated.
I think Dude's comment was aimed at the site moderators asking if they can put the name of the venue into the thread title, as this would encourage more people to read the thread.
I am not a big theatre goer, but a very big Ustinov fan - rather excessively so according to my family!
Did you ever listen to In All Directions? Another somewhat lost bit of Ustinov's work.
