Ozzy Osbourne has performed what he says is his final live show, thrilling 40,000 fans in Birmingham, England, on Saturday.

Reuniting onstage for the first time in two decades, Black Sabbath performed to a sold-out crowd of 40,000 with its all-star, one-day-only charity festival Back to the Beginning, held in Ozzy Osbourne’s hometown of Birmingham on July 5 and serving as a farewell concert to and celebration of the longtime rocker.

Ozzy Osbourne, following a set with his solo band, was joined by fellow Black Sabbath members to play songs like “Iron Man” and “Paranoid."
