Canada fans demand Britney ticket refund

Angry Britney Spears fans who were subjected to the 'Toxic' troublemaker's stage tantrum in Vancouver, Canada last week have set up a website in a bid to get their ticket money back.

A group of attendees are demanding a refund from Spears or promoters AEG Live for the money spent on attending the concert, which was abruptly halted without explanation so second-hand smoke could be cleared from the venue.

Spears, a smoker, took exception to the smoky atmosphere in GM Place and refused to perform, stopping her show for close to 40 minutes and leaving fans stunned.

As the houselights came up, many ticket buyers thought the concert had been cancelled - and left the venue.

Some 20 minutes into the stoppage an announcer explained the concert would not continue if people kept smoking - because it was "unsafe" for Spears and the performers.

Eventually Spears returned and finished the show, without addressing the stoppage.

And now some fans insist the concert was ruined for them, and they've set up a website to ask for a refund.

Others who attended the show and were equally put out by Spears' anti-smoke stance are being asked to add their names to RefundFromBritney.com.

Spears is now back in America on tour. She played the first of two Los Angeles shows on Thursday night.
