As classic Broadway musical A Chorus Line has been revived in the West End, with a cast that includes ex-EastEnder John Partridge (Zach) and Scarlett Strallen (Cassie).
The musical took shape in the mid-1970s when its creator Michael Bennett tape-recorded dancers telling their life stories.
Co-Director and choreographer Baayork Lee, who was involved in the original Broadway production and has a character in the show based on her own life, said the musical was the first type of reality show.
