Faced with participants who simply cannot sing, the ENO's world-class voice coaches set out on a journey of vocal transformation and narrow the group down to six.
The chosen six are faced with the daunting challenge of singing in front of each other. Coaches Nicky, Sarah and Michael prepare them with one-to-one tutorials.
The singers prepare to perform in public for the first time, with the scale of the audience unknown. Luckily, Welsh superstar mezzo-soprano Katherine Jenkins is on hand.
The singers reach the end of their journey and take on one final challenge: a live performance to a packed auditorium at the London Coliseum.
Produced by the English National Opera, Les Dennis stars in Gilbert and Sullivan's comic opera HMS PINAFORE - a hilarious tale of love, honour and duty.
