Tamsin Greig on the challenge of singing with a 'massive' tongue

Tamsin Greig is about to make her musical theatre debut in a musical adaptation of Pedro Almodovar's Oscar-nominated film Women on the Verge of a Nervous Breakdown.

Directed by Bartlett Sher at London's Playhouse Theatre, the cast also features Ricardo Afonso, Haydn Gwynne and Anna Skellern.

Greig, whose West End credits include Jumpy and The Little Dog Laughed, plays Pepa in the comedy, which focuses on the lives of a group of female friends in Madrid.

She tells BBC arts correspondent Tim Masters how she discovered her singing voice.
