I can sort of see what poppyshake is saying, as it is supposed to be a ballroom and a latin, and Charleston is neither, however, the salsa is not part of the official latin discipline either, but has been in the final for the last three years, so it's obviously never been a rule they've been stubborn about.
I thought tonights first show was great, particularly good to see Jade & Ian's tango - I've been waiting for that for weeks! - and I'm voting Team Cola. They may not be technically the best dancers, but I love the personality and spirit they bring to the floor. I did love Ricky & Natalie's quickstep, but I just find them so earnest and sincere - it doesn't seem genuine.
