I have it straight from the horses mouth ........
I was talking to JT this afternoon.
The move to the Bowling Club from the Duke is as permanent as things get.
For one reason or another it's not possible to return to the Duke.
The Thursday night arrangement at the Club will continue for a short while yet, but the Club night will eventually change to a Tuesday night as the Bowling Club will need Thursdays for functions during especially during Summer.
There's lots of plusses and a few minuses to changing to a Tuesday but JT feels it will all work out for the good , and he's been doing it for 40 odd years now.
He's also very pleased about the enthusiastic welcome he has received from the Club and says that the actual room is great for performing.
Good luck from me then.
