WATCH: Ozzy Osbourne Sings 'Bark At The Moon,' Gives Eclipse In Illinois A Soundtrack

CARTERVILLE, IL — When building the lineup for this year's Moonstock Music Festival, a four-day outdoor concert in southern Illinois designed around Monday's total solar eclipse, organizers sacrificed subtlety at the altar of spectacle when choosing the ideal performer to take the main stage during the celestial event's peak time. But more than a little showmanship was needed when you're trying to provide the soundtrack to the moon completely blotting out the sun, and Ozzy Osbourne singing "Bark at the Moon" in Carterville, Illinois — a location "marked as one of the best spots" to watch the eclipse for the longest duration, according to the festival — was a perfect choice. The only way concert promoters could have been more on the nose is if they had booked Bonnie Tyler perform "Total Eclipse of the Heart."

Osbourne took the stage at around 1:20 p.m. Monday, Aug. 21, and after nearly a minute into his 1983 single, the sky had darkened so much that it look like the rocker had begun his performance at 1:20 a.m., as a video by YouTube user Brianna Holder shows. By the end of the song, however, the sun was back in all its glory and order restored to the cosmos. Along with Ozzy's performance, Holder's video also gives a stunning view of the eclipse.

The four-day Moonstock began Friday, Aug. 18, at Walker's Bluff, a winery and vineyard in southern Illinois. The lineup also included rock and metal acts such as Five Finger Death Punch, Papa Roach and Theory of a Deadman. But the event only had two headliners Monday: Ozzy and the total solar eclipse. Festivities didn't begin and end with Osbourne and the eclipse, though. The festival held a post-eclipse party with performances by Psychedlic Love Machine and Pump.
