Strictly Come Dancing preview

It's all change in tomorrow's Strictly Come Dancing and not a moment too soon. There are two new dances plus a competitive Viennese Waltz.
The new dances are the Charleston and the rock and roll (if that is its correct title.) Natalie and Vincent, and Ricky Whittle and Natalie will be dancing the rock and roll and the other couples the Charleston (popularised by Josephine Baker, pictured.)
What's interesting about the new dances is that they're not known to the professional dancers, who were trained and choreographed by specialists.
From what I've seen on It Takes Two, Vincent has been struggling with the rock n roll which is a very demanding and physical dance. He seemed to be having more problems than his celebrity partner, Natalie Cassidy, although you wonder if the producers "stage" this to try to get us to watch the show on Saturday.
As usual there is another injury drama. This time it's Ali Bastian who injured her foot. Nonetheless she will bravely battle through even though the Charleston is very "foot intensive" (I can't think of a dance that isn't!).
I'm really looking forward to the competitive Viennese Waltz. Unlike the group dances, which are choreographed so that there's enough room for everyone, a competitive group dance is basically "every man for himself", and couples will have to navigate their way around the floor to avoid bumping into the others and to showcase their dance. It's a real throwback to the old-fashioned Come Dancing show. It will be hardest for the male celebrities because they will lack the knowledge, garnered by the professionals over years of competitive dancing, of "room craft" and how to slow down or speed up to ensure a clear path.
