It's Musicals Week on Strictly, meaning that remaining contestants Alex, Chris, Karim, Kelvin and Emma - minus Saffron, who was voted off last week - are keen to dazzle as they bring a taste of Broadway to the studio. However, it's also the quarter-final and with the final looming ever closer, the pressure is on. The extravaganza gets under way with a big opening number featuring none other than Craig Revel Horwood. Presented Tess Daly and Claudia Winkleman.
