Legendary heavy metal singer Ozzy Osbourne was a guest on today's (Tuesday, October 25) edition of the CBS program "The Talk", which is co-hosted by Osbourne's wife/manager Sharon. He discussed his new book, "Trust Me, I'm Dr. Ozzy: Advice From Rock's Ultimate Survivor", and "God Bless Ozzy Osbourne", the feature-length documentary that Ozzy's son, Jack Osbourne, co-produced. The entire episode can now be viewed at CBS.com. A couple of clips from the show are available below.Although Ozzy said at the start that his medical advice column was not meant to be taken seriously, he said on the October 13 edition of NBC-TV's "Today" show that he now thinks he's the perfect person to dispense health tips to people. Speaking with interviewer Jenna Hager, Ozzy said, "It started as a joke at first. I survived the rock 'n' roll lifestyle and the drinking and the drugs and I learned to tell the tale. People along the way would say what's this pill? What's that pill? Is this any good for that? And I'd go, 'Well, I've sampled quite a variety and so I think I thought it would be funny to do a spoof on that.'" Now, however, Ozzy is not joking about some of the advice he doles out, especially to young men, whom he says should seek out medical attention the minute they see a strange lump or rash. Ozzy said, "Go see your doctor, that's what they're there for." Ozzy said that his own paranoia about health made him convince his wife Sharon to visit a doctor when she was not feeling well. She ended up being diagnosed with colon cancer and getting successfully treated for it. Ozzy appeared on the "Today" show to promote his new book, "Trust Me, I'm Dr. Ozzy", which compiles the best advice from the column. The BLACK SABBATH singer who is in the early stages of reuniting with the group for a new album and tour said he's sober but "still crazy" nowadays, adding that sobriety allowed him to finally get his driver's license and buy his own car, a Ferrari.
