GLAMOROUS string quartet Escala who reached the finals of the TV show Britain's Got Talent, notched up another success after wowing a crowd packed with stars at a millionaires' charity dinner.

The band, which includes 24-year-old Izzy Johnston of Harpenden, played in front of celebrities such as Simon Cowell, key-note speaker Tony Blair, Uma Thurman and Bob Geldof at the Ark gala dinner last Thursday at the Old Royal Naval College in Greenwich, London.

And the quartet, whose other members are Chantal Leverton on viola, Tasya Hodges on cello, and Victoria Lyon on violin, were not intimidated by the rest of the line-up which included Stevie Wonder and received thunderous applause for their performance.

The dinner is a high-profile annual event attended by top hedge fund managers and City workers. It was attended by more than 1,000 people with tables reputed to have cost up to £100,000.

This year it raised £25million helped by auction lots such as a ticket to Nelson Mandela's 90th birthday and a Damien Hirst work of art.

Escala manager Alexander Lyon said the Ark performance was a real success and a great boost for the girls. They had received a lot more inquiries from people wanting them to perform as a result of getting through to the finals of ITV's Britain's Got Talent, and they were trying to play at as many gigs as possible without burning out, he added.

The group is currently on a one-month tour of the country as part of the show.
