It's nearly forty years since glam rock band Kiss formed in New York in 1973.

This week they've been in London, playing a sold-out concert in aid of the charity Help For Heroes.

Kiss also found time to launch one of the most expensive pieces of rock memorabilia ever made - a book which sells for nearly £3,000 per copy.

Emma Jones went backstage to meet the band.
