With James O'Brien.

Three minutes after 12, and so it begins, your weekly adventure, adventure, journey into the unknown.

0845, 6060973 is a number to call.

I may take a little longer than usual to set things up today because, well, for two reasons.

Number one, thanks to the success of the podcast, available via LBC.co.com.

UK and, of course, via iTunes as well.

We're getting loads and loads of new people tuning in.

They will know how it works, but if they've only listened on the podcast before,

they won't necessarily know how to join in or be minded to join in.

I seek to encourage them.

And the second reason is simply that we didn't do it last week.

George Osborne and the late Nelson Mandela conspired to robbers of a mystery hour last week with their autumn statement and my decision to dedicate the whole three hours of Friday's show to the

passing of Nelson Mandela. Unlike the BBC, we didn't need 100 people to do it. We just needed a

phone line and a microphone.

And thanks to you, I think, did the man proud.

I would describe this as the radio equivalent of those newspaper columns, which you've probably seen,

where readers write in with a question, notes and queries, I think they call it in the Guardian,

Q&A in the mail. It's a daily feature in a lot of papers.

And readers write in with something that's just got them puzzled.

It could be a matter of deep intellectual, scientific import.

It could be truly a question of life and death.

Or it could simply be something silly.
