Step 1 : Introduction to the question "Which rock star famously bit the head off of a bat while performing on stage?"
Ozzy Osbourne rose to prominence during the 1970s as the lead vocalist of the heavy metal band Black Sabbath. Osbourne achieved infamy overnight after an incident on Jan. 20, 1982, in Des Moines, Iowa. During the height of his drug problem, Osbourne was performing when an audience member threw a bat onstage. The singer, believing it was rubber, bit its head off, only to find out the bat was real and alive. According to Osbourne, the bat was not only alive but managed to bite him, resulting in Osbourne being treated for rabies.
