Ozzy Osbourne commemorated the final concert of his life just one day before his death. Osbourne shared a behind-the-scenes photo from Black Sabbath's Back to the Beginning show via Instagram on Monday, July 21. The picture showed the outside of Osbourne's dressing room at Aston, Birmingham, England's Villa Park, where the concert was held on July 5. "The Final Show," the poster read, featuring a photo of Osbourne and his Black Sabbath bandmates Geezer Butler, Tony Iommi and Bill Ward.
