Week 4 dances and songs

It's Tuesday so it's time for the reveal of the dances and song choices for each couple this week.  I've updated the Week 4 results page with the dance and song details and I've also updated the Songs page, but to help you see which of this weeks songs have been used before, here's an extract with them all in.

EDIT: The BBC blogger strikes again!  For the second week in a row, the BBC had one couples song choice wrong on their blog post.  Originally Robert & Oksana were listed as dancing to 'Shout' by Lulu, but on It Takes Two their song choice was announced as 'Boom Bang A Bang' by Lulu instead.  Thank goodness for that ... I'm not sure how on earth you could dance a Viennese Waltz to Shout!
