Let It Shine S01E05 - Episode 5

The boys left in the contest must now perform in groups for the first time. Each group collaborates with a big name in British music - Olly Murs, Kaiser Chiefs, Melanie C, Busted or Beverley Knight - and the collaborations feature three songs with each artist. Watch out for a spectacular opening number too.

This week's guest judge is Lulu, who famously collaborated with Take That. After each performance, Lulu, Dannii Minogue, Martin Kemp and Gary Barlow must choose five boys from each group to become the bands for next week's live shows.
