Jill & Darren's Jive
Ricky & Natalie's Quickstep

Also loved the Pro Quickstep that Natalie choreographed.

Matthew and Alesha's argentine tango.

I still have a screen grab from this on my wall at work.

I love you!! Thank you!! You wouldn't Adam & Eve how many different combinations of search terms I put in trying to find that

Yay...I'm glad I was able to find it for you then!

I love this thread! Thank you.

Without a shadow of doubt it has to be Mark and Karen's Argentine Tango - wow! The choreography was what other dances should be like, even pro ones! I've watched that dance so many times, and will do still.

Others include:
Louisa's jive (she was robbed!)
austine's paso
kelly's jive
jill's jive
racheal's argentine tango
Michelle's jive

But there are only a few I have to say - work on your dances pros!
