In a special LIVE performance, Paul Potts will sing his signature classic Nessun Dorma, exclusively for It Takes Two on Tuesday April 15 at 7.30pm on Seven.

Paul will be accompanied by a 34 piece orchestra comprising It Takes Two's strings and woodwind section augmented with brass, horn, tympani and harp musicians.

The unlikely winner of Britain's Got Talent, Paul Potts stunned the judging panel, including show creator and tough critic Simon Cowell, when he opened his mouth and started to sing.

The ex-mobile phone salesman strolled apologetically on to the stage to audition for the show, dressed in a bargain suit and looking nothing like a classical singer, announcing he was going to sing opera. The result was magical, his rendition of Nessun Dorma bought the audience to tears and his life changed instantly.

Since his high profile win, Paul has released a debut album One Chance and will make his only Australian performance live on It Takes Two on Tuesday night at 7.30pm.

For next week's It Takes Two semi-final, the three remaining couples will prepare a song from a genre they have not performed before as well as attempting their professional singing partner's hit in an attempt to make it through to the grand final.
