It’s week eight of Strictly Come Dancing 2009 .

Here is what you need to know about Saturday’s programme:

What’s the format for this weekend?

There are nine couples left in. Each is performing a different dance.

The two couples with lowest scores from a combination of judges' points and viewers’ votes will then face each other in a dance-off with the judges voting to save one of the couples. The other couple will leave the show.

The BBC’s blurb adds: the professional dancers treat us to a stunning Viennese waltz, and music is provided by the legendary Rod Stewart.

It should also mention that Rod’s wife Penny will dance with Matthew Cutler.

Who’s performing which dance?

• Ricky and Erin – salsa
• Chris and Ola – foxtrot
• Ali and Brian – Viennese waltz 
• Natalie and Vincent – quickstep
• Phil and Katya – rumba
• Laila and Anton – paso doble 
• Ricky and Natalie – tango
• Jade and Ian – jive
• Craig and Flavia – cha cha cha

When is the show on TV?

Saturday night
6:25pm to 8:15pm BBC One.

This year you can watch in high-definition on the BBC HD channel – available subscription-free on Freesat. For more information go to: www.freesat.co.uk

What coverage will this blog be providing?

We will be doing live coverage on this blog – superblogger herself Miss Bubbles will be in the hot seat for that so join her on Saturday night as the show starts. Once the show ends I get busy writing my usual full review of the night including blogger’s wife’s all important opinions on the dresses.

Do join in the discussion by using the comments section – as ever we love to read your views.

Who’s going to be eliminated?

Yes, it is time for my ever-reliable prediction. Last week I predicted Natalie Cassidy will lose to Ricky Groves in the dance-off. Wrong! Of course, if I had predicted Zoe vs Ali in the dance-off, I’d have been laughed off the internet before the show had started; it’s just so unpredictable this year.

The William Hill website offers the following odds for the week eight elimination:

Craig Kelly 5/6 
Chris Hollins 5/1 
Natalie Cassidy 6/1 
Ricky Groves 9/1 
Laila Rouass 14/1 
Jade Johnson 14/1 
Phil Tufnell 16/1 
Ali Bastian 20/1 
Ricky Whittle 66/1 

Last week I said Craig Kelly would make it to Blackpool and then the voting public would drop him like a stone.

I stand by that. There’s no point voting for him now he’s achieved his aim, although I wasn’t sure what the point of keeping him in for the past few weeks was anyway, poor soul.

So this week, I predict Craig Kelly will lose in the dance-off. But to whom? Pick a name, any name. They’ll all thrash Craig anyway and I can’t see the judges wanting to save him. Let’s say…Laila Rouass.
