Graffiti artist Banksy has caused a media storm today with his latest exhibition in Bristol. Banksy goes to great lengths to conceal his identity. The reason for this is because Banksy is already famous in another guise. Banksy is in fact shamed TV presenter Michael Barrymore. You can see it in the humour of such works as his hitchhiking Charles Manson. Straight out of the ‘Strike it lucky’ manual. Awight?
