U2 frontman Bono had to separate SIR Bob Geldof from Tony Blair to prevent him from spitting at the British Prime Minister. The crusading rocker came to the rescue after Geldof's discussion with the UK leader became so heated, he feared a saliva shower was on the way. He says, "I had to call him off Mr Blair. Literally spittle coming out, invective coming out, and Tony reaching over to me saying, 'I believe you've a greatest hits coming,' just to get a break from Geldof. "I have seen Geldof try to bite prime ministers. I accept the rules of ultimate fighting, which are: you can't poke someone in the eye or bite them, and Bob doesn't."
