Reliving the glory days of New York's Chelsea Hotel

When you think of New York in the nineteen-sixties and seventies - one place that may come to mind is the Chelsea Hotel. It was a hangout for celebrities and artists - including Andy Warhol, Bob Dylan and Janis Joplin. Now - (ANI) in an unusual auction - fifty of the hotel's doors are going up for sale. Each one a memento of a New York that no longer exists. The BBC's Tim Allman has more.
