The first play I remember seeing was "Stig of the Dump" at the Haymarket Theatre in Leicester! I was about 7 I think and it was the Christmas show. We shouted "jam jars" at each other for at least two years after! 
 
Before lock down I had tickets to see Metamorphosis... absolutely gutted that The Tron closed it's doors the night before!!! That would have been quite something I think!
