Singers face their day of destiny at the Royal Albert Hall when months of practising and mentoring are put to the final test tomorrow.

The 40 singers plucked from Blackbird Leys, Oxford, for a television experiment will swap their day jobs and step out in front of the television cameras as tenors, sopranos and altos.

But for one lucky singer it will not be the first time in recent weeks he has trod the boards at the Royal Albert Hall.

Producers for the documentary Ivor's Choir allowed tenor Eric Hall, 71, of Fry's Court to hold a personal performance for his wife at the famous live venue earlier this month.

Ann Hall, 53, could not make it to the Royal Albert Hall to join the hundreds of other spectators tomorrow due to ill health.

Mr Hall said: "It was a special day. I've got it on camera and taken it round to show all the girls in the choir.

"Ivor (conductor Ivor Setterfield) said she 'will go to the ball'. They put her in the Royal Box and she was the only one in the whole building apart from a few staff.

"But Thursday will be even better there will be so many more people. I don't get nervous."

The choir will share the stage at the Royal Albert Hall with classical music pop group G4.

Working mum Lissiea Davidson, 40, of Haldane Road, is hoping the performance will give her much-needed experience before auditioning for the X-Factor next month.

She said: "I'm not nervous at all, I'm really looking forward to it.

"All the practising has really helped and I'm pretty confident.

"The most challenging part has been juggling being a mum and working. It's been hard, but enjoyable."

The concert will be filmed for the Channel Five show Ivor's Choir and their performance can be heard on Classic FM.

All 40 singers work and live in Blackbird Leys and began their journey at demanding auditions at Blackbird Leys Community Centre in January.

After the lucky singers were chosen by conductor Ivor Setterfield they receiving weekly coaching, performed at the Kassam Stadium before an Oxford United football match, travelled to Italy for street singing and wowed the crowds at a special concert of family friends and guests in Blackbird Leys Park.

The choir's experiences over the past three months have been filmed for the television documentary, which will appear on the screen in the summer.
