Pop Idols Will and Gareth delighted fans with a surprise performance today as they announced plans for a new joint tour.

The pair made an unannounced appearance in London's Covent Garden piazza where they appeared with Pop Idol finalist Zoe Birkett.

The duo revealed they were to sing from the same song sheet on a national tour starting in October with 16-year-old Zoe in support.

The dates include a show at the Sheffield Arena on October 13.

Today hundreds of fans watched as the trio got up on stage to sing a selection of big band classics from their current album, backed by 16-piece band, The Big Blue.

Zoe opened the show with Get Happy, followed by Gareth singing Mack The Knife and Will's rendition of I Won't Dance.

Announcing plans for the nationwide tour, Will said: "We are really excited and it should be a real laugh."

Zoe said: "I am so excited and it's going to be really great fun to be with the two best looking guys in the UK."
