THOUSANDS of revellers watched as York Minster was bathed in colour during a stunning light show to celebrate the city's big Christmas lights switch-on.

An estimated crowd of 10,000 packed Duncombe Place to witness the spectacular sight of the Minster covered in white snowflakes with a stunning backdrop of changing colours.

The official switch-on was a joint effort between snooker player John Parrott, York Theatre Royal panto star Berwick Kaler, pop celebrities Hayley Bamford and Alistair Griffin, and civic dignitaries.

The whole event was broadcast live on television and radio.

Organiser Mark Brayshaw said it was believed more than 10,000 people came out for the event - an increase of almost 3,000 on last year.

After the switch-on, York's very own Pop Idol Hayley Bamford wowed the crowds, getting everyone in the mood with some Christmas songs.

The big surprise of the night was the appearance of Fame Academy's Alistair Griffin who decided to take part in the show at the last minute.

Fans screamed and cheered when the former York busker came on to the stage and performed his latest single.

Mark Brayshaw said the appearance had come about after Hayley Bamford's mum, who works with Alistair's sister, had mentioned Hayley's appearance, and Alistair said he would love to come along.

"It was a good example of local people all pulling together," said Mark.

Lisa McCloskey and her two-and-a-half-year-old son Calum, of Bishopthorpe, said they had a wonderful time.

Lisa said: "This is the first time we have been and we have had a really nice time. The Minster looks lovely."

Helen Edmondson, of Acaster Malbis, said: "The colours on the Minster are stunning."

Mark said the event, which takes a year of planning, had gone well.

"It is a family concert and a family atmosphere. Everybody was happy to see the Minster lit up.

"It was good family entertainment and everyone had a really good time.

"The switch-on takes a lot of planning, but it tends to be all last-minute as it goes out live on television."
