Rachel and Vincent - rumba and Argentine tango(sizzling)
Jill and Darren - jive ( the bees knees)
James and Cherie - rumba ( just so lovely)
Austin and Erin - rumba (makes me go all gooey)
Karen and mark - Argentine tango ( saucy)

I will probably rewatch harry and aliona Argentine tango..at some point. But to be honest this series hasnt stood out for me

I would watch Lilia's latin on an endless loop but the quality on youchoob is just not high enough.

Kara & Artem: american smooth, rumba, viennese waltz

Cherie & James: rumba

Ramps & Karen: Argentine tango

Ricky & Natalie: quickstep

Rachel and Vincent's Tango
Kara and Artem's American Smooth

I always re-watch Ann Widdecombe's Paso Doble, for two reasons mostly

1) Just to make sure it was as bad I think it was

2) Confirmation that I'm not the worst dancer in the country

http://www.youtube.com/watch?v=l2snk9HhLp0

Chris & Ola's Charleston
Austin & Erin's Tango
Matt & Aliona's American Smooth

And I know it's from this series but a special mention to Robbie & Ola's Jive, because:

1. I loved Robbie trying to look sexy (even though he did, a bit)
2. Bruno saying 'Oooh Robbie... Because you're worth it!'
3. And Len saying 'Well that's what we are Robbie, we're love men!'

This is going to sound ike an odd choice but Kara's very first dance (cha cha) where her costume was weird and she had that stumble as well, lol. Because despite those two elements it was a good showcase of what was to come from her (in terms of dance ability). She danced most of her dances well if not great, but I hated their Jive for some reason.

Also love Flavia & Matt Diangeo's America Smooth.
Liked Flvia & Matt's Tango too.
Quite liked Brendan & Lisa Snowdon's Tango.
LOVED Vincent & Rachel's A.Tango.
Liked James & Cherie's Rumba.
Liked Ola & Chris's Charleston.
Liked Vincent & Louisa's (was it a Jive)?
Loved Darren & Jill's JIVE !!!!
Liked Brendan & Lisa's cha cha.
Liked Katya & Phil's Tango.
Like Natalies Quickstep with (think it was Scott and not Ricky).
Liked Aliona & Harry's A.Tango.
LOVED Kristina & John's Paso! LOL.

I don't think to watch dances gone by that much but if I do this one is top of the tree for me ...it still gives me goosebumps watching it ....I think one of the reasons I think it is special is because firstly it's a rugby player and secondly it was week 1 so I wasn't expecting any of the dancers to be this good

Austin and Erin's waltz

http://www.youtube.com/watch?v=yfywk6-TZJw

Love it!

Bacofoil showdance - never fails to make me laugh out loud.

Austin and Erin's waltz, tango, foxtrot, paso, cha cha and jive (they wuz robbed blind and therefore I hate myself for watching the enemy showdance)

Vincent and Louisa's jive.

Jill and Darren's jive.

Mark and Karen's salsa and AT.

Pretty much any Kara and Artem dance.

This year I have re-watched Kristina and Jason's tango, Aliona and Harry's QS and most of Chelsee and Pasha's dances, especially the QS.

Anything with Kara and Artem...

From this season Jason's Tango will probably be the one I look back on

This pro dance (as have over a quarter of a million others on YouTube).

http://www.youtube.com/watch?v=haZaoiW3qMA

And this pro/celeb one, with nearly as many, (but different clips uploaded).

http://www.youtube.com/watch?v=cADiYeGJe7s

Almost any from Kara and Artem (not the jive or showdance), but especially the rumba (pink), VW and AS (Blackpool).....sigh

I wasn't a fan at the time, but occasionally look at Rachel and Vincent's AT and Rumba.

Alesha's Cha Cha (which doesn't stand up brilliantly, but at the time I stood and cheered in my sitting room!).

Matt C and Aliona's hip hop samba

Pro-jive to Rebel Yell

V and F's ATs - any/all, but not the 'unleashed' one
