He shot to fame earlier this year when he took to the Britain's Got Talent stage to sing a song he wrote about a girl he fancied but wouldn't tell Simon Cowell her name.

Ryan O'Shaughnessy went on to finish fifth in the competition and now he has been added to the list of acts set to star at Norfolk's biggest free pop festival this summer, it has been revealed.

Thousands of people are expected to pack King's Lynn's Tuesday Market Place on the final night of Festival Too, which Irish-born Ryan will perform.

He will appear on the same bill as British soul singer Lemar, who is well-known for hits including If There's Any Justice, It's Not That Easy, and 50/50 and is returning to Lynn by popular demand after performing at Festival Too in 2010.

X Factor favourite Marcus Collins and Ben Montague, one of the UK's brightest melodic rock talents, will also share the stage at the climax of the festival on Saturday, July 14.

The EDP is an official sponsor of Festival Too - one of Europe's largest free music festivals - and the final night is being brought to the town in association with Lynn-based radio station KLFM.

The festival kicked off with a fireworks spectacular on Monday, June 4, as part of the Queen's Diamond Jubilee celebrations.

There were performances from local band The Yesterdays and Queen tribute act The Bohemians, which was followed by the lighting of the Jubilee beacon and the fireworks display.

The Pigeon Detectives and The Brand New Heavies will take to the Tuesday Market Place stage for the festival's first weekend on July 6 and 7.

They will be supported by local acts the Coots, Jake Morrell, Kenza and Jessie's Ghost as well as Maltese singer Sophie Debattista, who represented her country at Junior Eurovision 2006.

There will then be performances by chart-toppers Soul II Soul, best known for their hit Back to Life (However Do You Want Me) and punk, ska and reggae band The Selecter on July 13.

Admission to all the gigs is free with sponsorship from local businesses helping to cover the cost of staging the event.

Festival Too started in 1985 with the aim of providing free entertainment to the people and visitors of West Norfolk and is now one of Europe's biggest free festivals.

Previous performers include Atomic Kitten, Deacon Blue, The Human League, 10cc, the Feeling and Sophie Ellis Bexter. American rocker Suzi Quatro is thought to have attracted one of the biggest crowds in the festival's history.
