Ozzy Osbourne and Black Sabbath have gone out with a bang at what they say will be their final gig, in front of 40,000 fans and supported by an all-star line-up of rock legends who have been influenced by the founding fathers of heavy metal, BBC reported.

Ozzy, 76, who has Parkinson’s disease, sang while seated on a black throne — clapping, waving his arms and pulling wild-eyed looks, just like old times. He appeared overwhelmed at some moments. “You have no idea how I feel. Thank you from the bottom of my heart,” he told the crowd at Villa Park in Birmingham.

He was joined by the full original Sabbath line-up for the first time in 20 years. The show’s bill also included fellow rock gods Metallica, Guns N’ Roses, Slayer, the Rolling Stones’ Ronnie Wood and Aerosmith’s Steven Tyler.

Wearing a leather overcoat and gold armband bearing his name, Ozzy rose from below the stage in his throne to a huge roar from the crowd. “Are you ready? Let the madness begin,” he called. “It’s so good to be on this stage. You have no idea,” he told the crowd, who responded by chanting his name.

After playing five songs from his solo career, Ozzy was joined by his Sabbath bandmates — guitarist Tony Iommi, bassist and lyricist Geezer Butler, and drummer Bill Ward — for four more, finishing with 1970 classic Paranoid.

Fans came from across the globe — if they could get tickets — for the all-day Back to the Beginning gig at Aston Villa’s football stadium, a stone’s throw from Ozzy’s childhood home. The star-studded show was dubbed the “heavy metal Live Aid”, and profits will go to charity.
