Comedian Chris Rock has brushed aside the controversy surrounding his foul-mouthed appearance at Live Earth London on Saturday (07Jul07). BBC television bosses took the U.S. star off the air just 10 seconds after he stepped onstage at Wembley Stadium to introduce the Red Hot Chili Peppers, because he swore at the crowd. Local TV host Jonathan Ross had to apologise to viewers for Rock's bad language. But an unrepentant Rock says, "I like to say those things. It's not good weed if you don't choke."
