Today (Feb. 17) in rock and metal news, Black Sabbath canceled all but one of their tour dates due to Tony Iommi's ongoing battle with lymphoma. However, those gigs will now be played by Ozzy Osbourne and a cast of all-star musicians. Also, Chris Cornell performed a rousing version of 'I Will Always Love You' last night in honor of Whitney Houston.

Elsewhere, Green Day's Billie Joe Armstrong celebrated his 40th birthday; Dave Grohl issued a clarification on his Grammy acceptance speech; Five Finger Death Punch debuted a new video; Ministry's Al Jourgensen rips into the Republican Party; Hellyeah and Clutch announced a co-headlining tour, and a whole lot more.
