pbr This year's Oxjam festival has attracted plenty of big names including X Factor star Diana Vickers.br ppbr She was one of three acts to perform at an Oxfam store on Tuesday night as part of the charity's month long fundraising event.br ppbr Diana, who was used to performing to large audiences while part of ITV's talent show, explained doing gigs in intimate venues can be just as tough:br ppbr She said:'' I get equally nervous, it is refreshing though to do a gig in a different environment.''br ppbr Since the first Oxjam festival in 2006, the project has raised more than £1.2 million in total for Oxfam's work.
