"To be with them on that day, it was like a magical dream." Smashing Pumpkins' Billy Corgan shares his memories of Black Sabbath's emotional farewell show, and his thoughts on the death of Ozzy Osbourne

Black Sabbath's star-studded Back To The Beginning extravaganza - which featured both the last-ever performance from the legendary quartet's original line-up and a final bow from frontman Ozzy Osbourne as a solo artist - was an emotional day for all in attendance, artists and audience alike.

But Smashing Pumpkins frontman Billy Corgan has admitted that the weight of the occasion actually caused him to burst into tears before the gates of Villa Park were even opened to the public on July 5, as he was one of a handful of people privileged to be inside Aston Villa's home ground two days earlier, on July 3, when a seated Ozzy Osbourne, guitarist Tony Iommi, bassist Geezer Butler and drummer Bill Ward soundchecked for their big night.
