This is LBC from Global, leading Britain's conversation, mystery hour with James O'Brien.

Four minutes after 12 is the time, and here we are our weekly adventure into the unknown.

Actually, that doesn't work at the moment, does it? Every flipping hour of every flipping program is an adventure into the unknown.

But this at least is deliberate and intentional. And it is your weekly opportunity to achieve the sort of satisfaction,

not ordinarily available anywhere else on your radio dial. The number you need is the same as

always. 0345, 6060973. And the way it works is this.

You've got a little question or possibly a big question, maybe even a medium-sized one,

bubbling away in the back of your brain to which you know there must be an answer,

but you have thus far been able to find it, unable to find it.

Somebody else listening to this program, which is lucky enough to have by far the best informed and intellectual audience of any radio program in the world

But equally, repetition we try to avoid, although frankly that rule's gone by the wayside as the years have passed. If I can remember dealing with a question relatively recently, then I will discourage my colleagues from putting it on the board again. Other than that, fill your boots. If you ring in with an answer, it has to be from your knowledge base already established.

You can't look stuff up, otherwise it's a complete waste of all our time.

The question becomes one of qualifications, to which you can answer by saying something

as banal as I saw it on telly last night, James.

You don't have to have a PhD in the relevant subject, will become clear when some of the questions are asked and they are

a curious mixture of the sublime the silly the serious and the downright stupid almost all welcome

um I think that'll do it right I think I'll solve one mystery for you at the beginning I told

you Stephen had uh had tweeted me to say my money's on Johnny Vaughn, and I wondered what on earth he was responding to. He's been back in touch to remind us that I had actually revealed that another radio presenter had been in touch to say that they too found a curious lack of conviction that Tom Watson's resignation as deputy leader of the Labour Party was
