A lot of the biggest rock stars came from next to nothing, and have had very ordinary, very blue-collar jobs before they hit it big....Rod Stewart and the Clash's Joe Srummer both spent some of their younger years digging graves...David Lee Roth was a hospital orderly, cleaning bedpans and all the other stuff orderlies did back then...it was Tony Iommi's last day as a sheet metal worker that the Black Sabbath guitarist severed the tips of two fingers, and still went on to become a bad-ass guitarist....John Bon Jovi made Christmas decorations, Nirvana's Kurt Cobain was a janitor, and Mick Jagger ran errands at a psychiatric hospital....here's more about all those, plus more rockers and their early jobs.
