Been said before but if the semi final judgment is based on performance surely there must be a balance in the dances each must perform

One ballroom
One Latin

If you really wish to witness progress then foxtrot QS Tango or waltz as one dance

This ensures we see at least one dance in hold so key in judgement

A segue of 2 or 3 dances would be brilliant but I don't think the dart throwing music monkeys would be able to cope with the challenge of choosing suitable music for the celebs to dance to.

Then again, their choices are so random anyway......
