Ozzy Osbourne has announced that he's going on his final tour. But, don't worry, you'll have plenty of chances to see him. The tour will kick off in 2018 and, according to the Ozzman's management, "likely" end sometime in 2020. The final touring lineup will be guitarist Zakk Wylde, bassist Rob "Blasko" Nicholson, drummer Tommy Clufetos and Adam Wakeman on keyboards. In a press release Ozzy boldly proclaimed: "People keep asking me when I'm retiring. This will be my final world tour, but I can't say I won't do some shows here and there."
