Not a single celebrity toe had even touched the dance floor before this series made the news with an explosion of indignation about the departure of judge Arlene Phillips. This shake-up will undoubtedly alter the dynamic of the show: it's hard to imagine either of the new judges - ballerina Darcy Bussell and season-five winner Alesha Dixon - being as cuttingly critical as Arlene. But Strictly is bigger than any individual, so we doubt there'll be much of a dent in its viewing figures. There are other changes afoot, too: for the first two weeks, eight couples will perform on the Friday and Saturday with one couple being voted off after Saturday's show. After that it reverts to just a Saturday show with the remaining 14 couples being gradually whittled down to three. As always, it's hard to guess who'll be the twinkletoes and who'll be the clodhoppers, but the bookies already have their eye on ex-boxer Joe Calzaghe, despite his admission that, "I've never really danced before. Maybe after a few beers in the club, in a quiet corner, I'd try to move a little bit, but I wouldn't say dance."
