James and Oliver duet with their dance captain Matthew to a medley of On Broadway by George Benson, New York, New York by Leonard Bernstein and You Can’t Stop The Beat from Hairspray Live!
Leading the charge to discover the greatest dancer are three superstar dance captains - platinum-selling singer Cheryl, Broadway and Glee star Matthew Morrison and Strictly Come Dancing professional Oti Mabuse.
The series is hosted by singer and presenter Alesha Dixon and Jordan Banjo, member of multi-award-winning dance troupe Diversity.
The four finalists take to the stage one last time, competing to win £50,000 and a chance to dance on Strictly Come Dancing. This week the four remaining acts will start by performing a collaboration with their dance captain. One act will then be voted off the show. The remaining three acts will then perform a second time, reimagining the audition performance that won the hearts of the audience. Who will give the performance of a lifetime and become The Greatest Dancer?
