Ozzy Osbourne had a long friendship with Motörhead frontman Lemmy Kilmister, and the two musicians now have something eerily in common in death. Both hard rock legends died exactly 17 days after powering through their final concerts amid illness.

When Ozzy Osbourne passed away on July 22, many fans were surprised to learn that he was no longer living in Los Angeles. The Black Sabbath lead singer and his wife, Sharon Osbourne, relocated to England — a plan that was long in the works.
