Watch OZZY OSBOURNE Perform 'Bark At The Moon' During Solar Eclipse

Ozzy Osbourne performed Monday afternoon during a solar eclipse at a festival in Illinois.

The BLACK SABBATH singer headlined Carterville's Moonstock festival, and he played his classic song "Bark At The Moon" at the height of the eclipse at 1:20 p.m. local time.

According to The Southern Illinoisan, Ozzy walked on stage at Walker's Bluff as the first diamond ring of the eclipse appeared, and began to sing the song as the shadow of the moon swept across the crowd.

"I don't think I've ever been in this part of the world before," Osbourne told his fans. "I love you all. Thank you for coming to see me."

Nearly twelve thousand people reportedly turned up to see the eclipse and Osbourne at Walker's Bluff.

Cynde Bunch, owner of Walker's Bluff, told The Southern Illinoisan one-fourth of the tickets sales were from outside the U.S.

"In the campground, we have thirty campers from different states and twelve camp sites rented by people from outside the country," Bunch said.

Ozzy is joined on the current run of dates by guitarist Zakk Wylde, who was the SABBATH frontman's regular axeman from 1988 to 2007, although they've often performed together since then. Osbourne's touring lineup also includes Rob "Blasko" Nicholson on bass, Tommy Clufetos on drums and Adam Wakeman on keyboards.

Wylde originally joined Osbourne's band three decades ago and backed the legendary frontman from 1987 to 1995, then again in 1998, from 2001 to 2004 and also from 2006 to 2009. His guitar playing can be heard on Osbourne's studio albums "No Rest For The Wicked", "No More Tears", "Ozzmosis", "Down To Earth", "Under Cover" and "Black Rain". The first album with Wylde went double platinum and "No More Tears" remains Ozzy's most successful album, going four times platinum in the United States with four Top 10 songs on the U.S. Billboard chart. Wylde also appeared with Ozzy on three live albums.
