KISS frontman Gene Simmons pays tribute to Ozzy Osbourne on "CBS Mornings," calling the Black Sabbath legend a "pure human being."

Ozzy Osbourne, the pioneering heavy metal singer who rose to prominence in the early ‘70s with Black Sabbath before establishing a successful solo career and playing himself on reality TV, died Tuesday. He was 76.

But no one was more surprised at the success of what became Black Sabbath than Ozzy himself. Ozzy, who died this week at the age of 76, once said the thing he was most proud of was that his band was not the creation of some music mogul.

Ozzy Osbourne's passing at 76 prompted Kermit the Frog to share heartfelt memories, celebrating their joyful encounters and the legendary musician's lasting influence on rock and children's entertainment.
