Anthrax rocker John Bush has been forced to supplement his rock 'n' roll income by making commercials for fast food giant Burger King. The heavy rocker claims he hasn't made enough money from his 15 year career in the band to give up work completely. Bush, who replaced JOEY BELLADONNA as lead singer in 1992, says, "I like doing it. It wasn't like I was sitting back and relying on my giant, enormous savings! I still had to work."
