主播大秀

International Broadcast Centre, Beijing

On Sunday afternoon a global audience of many billions will watch the Olympics closing ceremony in Beijing's Bird's Nest.

A chance for China to bid farewell to the Games - probably with a huge collective sigh of relief at pulling off such a magnificent sporting show, without (so far) the feared protests, pollution and positive drug test fest, talk of which dogged the build up.

Normally, that would be it, the British media would pack up and go home along with the athletes and we'd all remind ourselves what a football looks like.

Just in case you'd forgotten, this time round it's different as for Britain it's the start of our four-year journey to host the greatest show on earth.

There will be an eight-minute segment in Sunday's ceremony (starts 1300 BST) when the Olympic flag is handed to London mayor Boris Johnson (let's hope he combs his hair), and 2012 organisers get the chance to give a little foretaste of what is to come.

On paper, the signs are not great - it's an open secret that we'll see David Beckham and Leona Lewis on top of a London bus.

But a colleague (a hard-bitten hack not prone to letting sporting authorities of the hook) who is privy to the details but has been sworn to secrecy, says the soundtrack is "fantastic" and that we'll all be pleasantly surprised.

The ceremony will be relayed live in the UK on all 主播大秀 outlets - and also shown on the network of big screens up and down the country - and organisers hope it will spark a similar sense of excitement we saw back in 2005 when the Games were awarded.

They want people to film themselves celebrating - and post the video on their 2012 You Tube site, with the best ones shown on the big screens.

- it certainly got me in the mood.

So anyway - as the focus switches to London - I'm interested to know what you'd like to know about Britain's preparations for 2012.

If you have any burning questions - about the organisation, the building, the funding, the likely stars, let me know and we'll get the answers for you.

The Games are (nearly) over; let the Games begin.
