Two of the Northern Ireland performers who reached the finals of the BBC’s search for a Nancy to star in the West End are to take part in this Saturday's Proms in the Park at Belfast City Hall.

Bangor's Niamh Perry and Belfast-born Rachel Tucker, who took part in I'd Do Anything with Lord Andrew Lloyd Webber, will join former BBC Young Musician of the Year winners Peter Moore and Jennifer Pike, the Irish traditional music group Altan, top Irish soprano Cara O'Sullivan and the Ulster Orchestra in Saturday night's performance.

The Belfast concert will be recorded by Landseer Productions and televised later this year by BBC Northern Ireland. This will be the Ulster Orchestra's second appearance in this year's prestigious BBC Proms series.

Early in August they performed live in the Royal Albert hall with the young Dublin pianist Finghin Collins, and received favourable reviews in the UK national press.

Hundreds of people will crowd into the grounds of Belfast's City Hall for the concert on Saturday, and there will be a traditional party atmosphere with picnic hampers, big screens and lighting displays.

The BBC said that all complementary tickets have been allocated, but any returns will be distributed on the the night on a first come, first served basis.

“There has been a big demand for tickets,” a BBC spokesman said. “Ticket holders will be admitted from 6.30pm and non-ticket holders will be admitted after 8pm, if capacity permits.”

Belfast Lord Mayor, Tom Hartley, said: “Events such as the Proms are not only good for the people of the city, they are also vital in helping to promote a positive image of Belfast to a wider audience, and so benefiting the profile of the city as a tourist attraction.”
