Sharon Osbourne visits her husband Ozzy's grave every day, she told BBC News as the family prepares to release a documentary about his final concert.

Ozzy Osbourne died 15 months ago at age 76 at his home in Buckinghamshire, just under three weeks after performing a farewell show with Black Sabbath at Birmingham's Villa Park. He had struggled with Parkinson's disease, a fractured vertebra and other health conditions for years.

Sharon described his final moments. "We'd spoken in the night. Ozzy had woken in the night and he asked me to kiss him twice, and I did," she recalled. "And then he said, 'Hold me, hold me tight,' and I did." The next morning, he woke early for his usual workout. Shortly after, he suffered a heart attack. An air ambulance was called but paramedics could not save him.

Sharon chose to bury Ozzy in the family garden rather than a public graveyard. "There was no way I could put Ozzy in a public graveyard," she said. "I've seen what happens to other people in the public eye. There's no peace because people want to come and they want to pay their respects. That's an ongoing thing, and I wanted Ozzy to rest and just be." She still talks to him regularly.

Despite his deteriorating health, Ozzy was determined to perform at that final concert. Doctors warned him against it two weeks before the show. "They came to see us at the house and they said, 'You can't do this. We're advising you not to do this. Your heart's too weak'," Sharon recalled. He performed seated on a throne and appeared energised by the moment and the crowd's support.

The new documentary, titled Back To The Beginning, features over 25 songs from the concert, including Ozzy's solo set and Black Sabbath's full performance. It includes backstage footage with fellow performers including Metallica's James Hetfield and Yungblud discussing Ozzy's influence.

Thousands of people lined Birmingham's streets at his funeral last July, laying flowers and singing Black Sabbath songs. Sharon said the public response brought comfort to the family. The flowers were composted for the family garden where Ozzy is buried.
