OZZY OSBOURNE: Footage From San Francisco Book Signing

Legendary heavy metal singer Ozzy Osbourne signed copies of his new book, "Trust Me, I'm Dr. Ozzy: Advice From Rock's Ultimate Survivor", yesterday (Saturday, October 22) at The Booksmith in San Francisco, California. Fan-filmed video footage from the event can be seen below.

In "Trust Me, I'm Dr. Ozzy", Osbourne embraces his status as a medical marvel to tell incredible stories, offer advice as only he can and shed light on his seemingly superhuman ability to stay alive. Released on October 11, "Trust Me, I'm Dr. Ozzy: Advice From Rock's Ultimate Survivor" by Ozzy Osbourne with Chris Ayres (Grand Central Publishing) is the follow-up to 2010's New York Times bestselling memoir "I Am Ozzy", which landed at #2 and #3 on the New York Times and Wall Street Journal non-fiction charts, respectively.

Based on his ongoing Rolling Stone (U.S.) Sunday Times (U.K.) columns, "Trust Me, I'm Dr. Ozzy" will include some of the best material from the columns, as well as survival stories not found in Ozzy's memoir, his answers to celebrities' medical questions, charts and sidebars, and much more. The best way to describe this book is 100% Ozzy part memoir and part advice column, delivered with Ozzy's famous wit and humor. It's comprised of reader-submitted medical and lifestyle questions, Ozzy digs deep into his murky past, searching for pearls of "wisdom."

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.

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.
