Pre COVID, there was no reason at all to have to go to the centre of London to see a live musical production; or any other live stage production, come to that. Leicester has the fabulous Curve Theatre which has hosted some wonderful original and touring stage productions. Stoke has the Regent Theatre, which, in normal times, attracts a lot of famous actors and performers. Living "out in the sticks" doesn't mean you can't access live theatre. You just have to want to.
Not my cup of tea, but he is a naturist and loved it I loved Oh Calcutta too but I didn't think you had to be a naturist to enjoy it!
