If you go to the club's website (
https://fvvmc.co.uk/theclub), the chairman's message talks about "The Speech House Show". If it's good enough for him...
And back in 2017 as my report says, it rained during the day and the ground was so wet from recent rain that only the Trotter was able to move.
In fact, I've now looked it up and the figures do show that September in the FoD is actually less wet on average than August, I certainly was not aware of the 'wedding angle'.
I do wish the show well, it's never been advertised as a 'steam show' although I think their publicity used to include a picture of a steam engine. As you say, it's a charity event and the organisers are in the best position to know what their punters want.
