Jazz singer Jamie Cullum is backing a campaign to save the venue where he played his first ever gig after bosses proposed plans to transform it into a restaurant. The Bull's Head in Barnes, London has been a popular haunt for jazz players and fans since 1959. Cullum played his first show there when he was 19 and he has been left devastated after discovering brewery bosses who have purchased the property are planning to relaunch it as a posh eaterie. Taking to Twitter.com, the Brit has urged his followers to sign an online petition in a bid to save the music space, writing, "My very first gig London was at The Bull's Head in Barnes when I was 19 with a band called the Alex Jackson Quartet. "I've since played there many times and seen many of my heroes there including the great Stan Tracey. It has been providing that service since 1959 and is a national institution. The new owners Youngs (brewery) want to turn it into a gastro pub (a bar selling food). You can help to stop this from happening and help save a great music venue by signing this petition."
