Colourful heavy rockers TWISTED SISTER have been forced to scrap a concert in California due to poor ticket sales.

The gig at the Bren Events Center in Irvine was planned by two entrepreneurial fans who took out a $100,000 (£50,000) bank loan to fund the 14 December (07) show.

Blabbermouth.net reports the Newport Beach, California couple stood to earn a tidy fortune for local charities and cover their loan if the show was a sell-out, but now it looks as if the pair will be left out of pocket after only 600 of the 4,300 tickets sold.
