Spice Girls singer Mel C joined the West End School of Rock – The Musical on Thursday for a surprise encore performance of her former group's 1996 hit "Wannabe" at the New London Theatre.
The production's all-kid cast of musicians, along with leading man David Fynn, opened the guitar-oriented take on "Wannabe" before introducing Mel C for a full verse. The winding performance featured lots of vocal swapping, a snippet of Aerosmith's classic "Walk This Way" and Fynn putting his spin on the track's rapped section.
School of Rock – The Musical is based on the titular 2003 Richard Linklater film, which starred Jack Black as a would-be rock star who finds his long-coveted backing band while posing as a substitute teacher. During a 2016 rehearsal for the Broadway production, Guns N' Roses guitarist Slash joined the young musicians for a live version of rock classic "Sweet Child O' Mine."
