Black Sabbath will be getting the royal treatment from four of their biggest fans: Metallica. In an announcement on their Web site, Metallica expressed their humility at the opportunity to induct the legendary metal band into the Rock and Roll Hall of Fame this year and to perform a few of their songs. Says the band, “For all of us in Metallica, Black Sabbath are a major influence not only on our music, but on our lives, and as you can imagine, we’re psyched to join Bill, Geezer, Ozzy, and Tony for the induction ceremony.”http://www.billboard.com/bbcom/news/article_display.jsp?vnu_content_id=1002155279
