Ozzy Osbourne inspired an emotional tribute penned by Black Sabbath bassist Geezer Butler following the frontman's death.

Few people knew Ozzy Osbourne more intimately than his Black Sabbath bandmates, who, despite their conflicts over the years, spent decades with the Prince of Darkness. To Geezer Butler, however, Osbourne wasn’t the Prince of Darkness at all; he was the “Prince of Laughter,” as the bassist wrote in a tribute to his old friend for The Times.
