Ozzy Osbourne

"It's time," the Prince of Darkness explains, admitting he's become a "homebody."

The singer says training for the gig is "like starting all over again."

On their first tours apart, Black Sabbath and Ozzy Osbourne took different approaches to their shared back catalog.

AC/DC, Ozzy Osbourne, U2, the Police, Guns N' Roses, Journey, Def Leppard and Van Halen are still standing.

After scoring some impressive round-one victories, 16 albums move on to even tougher battles.

Rock's biggest acts entered the new decade with new lineups, new sounds and new facial hair.

Guns N' Roses and Tool have also been added to July's star-studded "Back to the Beginning" concert.

Reworked version of 2015 song will appear on deluxe digital edition of 'The Morrison Project,' out next week.

Keeping the big game rocking!

"For all my complaining, I'm still alive," Prince of Darkness marvels ahead of his final show this summer.
