He was one-fourth of the biggest metal band in the world for over 15 years -- can you recognize him from this somewhat grainy school photo?

Need a clue or two? OK, this photo was taken in 1978, when our hero was in the 8th grade. Years later, he would leave one well-regarded band to join one of the most popular groups in the world. He helped his new bandmates to reach even higher heights over the next decade and a half before leaving for his own peace of mind. Think you know who we're talking about? Find out here!
