If it wasn't for that moment, Alex and Sam wouldn't be lost in their favourite track at the club.

They wouldn't have shared that electric night front row at a music festival.

Or bonded over techno records talking all night long until the sun came up.

The promise that I issue to you is that by 1 o'clock today you will know more than you do now.

LBC 97.3 Mystery Hour with James O'Brien.

And so it begins. Your weekly opportunity to get satisfaction.

Ooh, matron. Indeed, to get a solution to whatever problem has plagued you. Calm down, Kay. Just

texted 84850 to say, what has happened to Mystery Hour? Well, it's here now. It'd be Mystery

Obviously, the Leveson inquiry, slightly rejigging things on the programme and indeed the station to wit.

Please don't miss tonight's Leverson special with a dizzying array of guests and pundits and expert comments, including Simon Kellner, former editor of the independent newspaper.

All that after 7 o'clock this evening with Ian Dale back in the chair,
