I loved the opening number. Probably my favourite pro-dance since the 'roxtrot' in series 7 with Brendan, Katya, Matthew and Aliona - although I prefer Team Ka$ha to Brendan and Katya as a partnership, so I thing this one just edges it for me.
It would be nice if the pro who choreographed a routine got a mention - on DWTS they often say "choreographed by......." The last time I remember SCD doing this was the series 8 launch show, where Karen Hardy and Matthew Cutler each choreographed the opening routines and were credited for it on air (the "choreographed by our professional dancers" from the series 9 launch show doesn't count - it's too vague!)
This routine made me realise how much I miss the pro-routines from previous years - the Rebel Yell jive, the Predict a Riot Paso, the Natalie-choreographed quickstep in series 7............ *scurries off to youtube*
