And capping a day of festival line-up changes, rumors, and sperm-related news, we learn that the latest rumor regarding troubled ol’ Ozzfest is that the metal revue might be transplanted to London’s O2 arena this July. A U.S. Ozzfest may also still be a go, whether as a full tour or a single multi-day event, but considering the U.K gave us Ozzy in the first place, it’d only be fair if they took him back.
