He's got to be pretty busy with Black Sabbath these days, what with the band's upcoming album and latest tour, but that didn't keep Ozzy Osbourne from turning out to support a good cause on Saturday (May 18).

Part of a rather eclectic bill lineup that also included Natasha Bedingfield and Sia, Osbourne was on hand to entertain the crowd at this year's 'An Evening with Women,' a fundraising event created to help raise money to support the L.A. Gay & Lesbian Center's efforts on behalf of women and girls.

Taking the stage with a solo band that included guitarists Steve Stevens and Billy Morrison, Dream Theater keyboard player Derek Sherinian, and drummer Tommy Clufetos, Osbourne delivered a set that included 'War Pigs' -- and, which you'll see in the fan-shot clip we've embedded above, contained enough thunderous volume to vibrate the smartphones in the audience (not to mention overwhelming their microphones in the process).

Happily for fans who've been worried about Osbourne's marriage in the wake of split rumors and his recent stint in rehab, Ozzy spent the non-performance part of his evening with a couple of the most important women in his life: his wife Sharon and his daughter Kelly, with whom he was photographed laughing and smooching on the red carpet. Looks like all's well in Ozzy's world just in time for him to start promoting the new Sabbath record in earnest.
