Former DIO guitarist Vivian Campbell has revealed plans to reboot the original lineup of DIO with new singer Andy Freeman, who he vows will "do justice" to the fallen frontman's legacy.

The Def Leppard and Thin Lizzy axeman had a rocky relationship with the former Black Sabbath frontman, who passed away in 2010. But the guitarist has always insisted he was proud of the work he did on the first three DIO albums.

Now he's confirmed a reunion with drummer Vinny Appice, bassist Jimmy Bain and keyboardist Claude Schnell, two months after they jammed together.

That was brought about when Campbell jammed Rainbow in the Dark with Steel Panther in January
