They started off as 40 singers but Ivor's Choir has dwindled to single figures now the TV adventure is over.

While television viewers are following the journey of an amateur choir as they sing their way from Blackbird Leys to the Royal Albert Hall only two thirds of the group has agreed to carry on now that filming has finished.

But an appearance of Ivor's Choir at the opening of the Blackbird Leys Leisure Centre was attended by just nine singers earlier this month and only 16 have agreed to sing at a scheduled party in July.

What is left of the choir will meet Fivearts Cities on Monday to decide whether to continue.

The first episode of the four-part series on Sunday called The Singing Estate attracted less than 1m viewers on Channel Five, compared to an average audience of 6.6m which tuned in to watch Portugal play Angola in a World Cup clash on ITV at the same time.

Now some choir members have cast doubt over whether Ivor's Choir will continue.

Tenor Eric Hall, 71, of Fry's Hill, in Greater Leys, believed the group would wind up.

He said: "I'm very hurt we are not carrying on. It's been fun and it's been an experience and I'd like to go on and on.

"I'm upset because we had a beautiful sound and I would like to hear that sound again.

"It sounds good when we have 12 or 16 for a harmony piece but without the 40 it is not the same and I feel very sorry to see everyone pack up.

"Last time there was just nine of us and it was very disappointing."

A meeting last week with television executives revealed less than 30 wanted to continue as Ivor's Choir and talks will continue on Monday.

The choir currently does not have a conductor.

Soprano Cindy Reid, 50, a music teacher at Mabel Prichard Special School, has already quit to rejoin her gospel group at the Christian Life Centre, in Cowley.

She said: "It is a shame because it was fantastic but it was for that moment and those that feel the need to will keep it going. I'm a jazz and gospel singer and the choir gave me encouragement to move forward."

Alun Evans, 41, of Aston Square, in Greater Leys, said: "I'd like to stay with the choir.

"I enjoyed it very much indeed and I think a lot of people thought it was a shame when the filming came to an end.

"The reason only nine people turned up was because it was hastily arranged and many were working."

A Fivearts Cities spokesman denied the choir had split but stressed that singers are free to make their own decisions for the future.

Spokesman Louise Plank said: "The most important thing is that they embrace whatever musical genre they want to and continue to pursue activities.

"I'd be delighted if they wanted to carry on together but many of them loved the experience and may want to go on to do other things."

A Channel Five spokesman said it was not disappointed with Sunday's viewing figures.
