A photo of BLACK SABBATH legends Ozzy Osbourne and Geezer Butler with the four members of METALLICA taken earlier tonight (Saturday, December 10) backstage at the Fillmore in San Francisco, California prior to METALLICA‘s fourth and final intimate show as part of the week-long celebration of its 30th anniversary as a band for fan club members only can be seen below. Ozzy and Geezer are expected to join METALLICA on stage to perform the SABBATH classic “Iron Man”.

A few years ago, METALLICA frontman James Hetfield told Rolling Stone magazine that he was surprised at how choked up he’d gotten while honoring BLACK SABBATH at the Rock and Roll Hall of Fame induction ceremony in March 2006 at the Waldorf-Astoria Hotel in New York City. Hetfield — dressed in black jeans and a black shirt amid a sea of tuxedos — fought back tears as he recalled a young James, nine years old, stealing SABBATH records from his older brother. “Those monstrous riffs lived inside of him and spoke the feelings he could never put into words, sending chills of inspiration through him,” Hetfield said. “They helped crack the shell he was stuck in. . . They have spread their wonderful disease through generations of musicians.” (Read the full text of METALICA‘s induction speech at this location.)

Afterward, Hetfield told Rolling Stone, “It was like, ‘Oh, no, I’m going to start crying,'” he said. “I’d never known it until I had to access all those emotions in front of that crowd, but it just goes to show how much SABBATH mean.” Following Ulrich and Hetfield‘s induction speeches, METALLICA blew the roof off the ballroom (for the first time ever at the Rock Hall ceremony, earplugs were distributed to the guests) with obsessively rehearsed covers of SABBATH‘s “Hole in the Sky” and “Iron Man”.
