He gave to the world Randy Rhoads. Despite his many transgressions, there is nothing that can be held against Ozzy other than Bark at the Moon which, sucked oh so horribly bad yet still, survives criticism because of the gift known as Randy. Randy trumps all ever held against Ozzy. E v e r.
Randy Rhoads didn't play on bark at the moon. He was dead. But I love the guitar in that song by the Jake Lee guy. Unfortunately he and the bassist wrote all the music and lyrics and Sharon Satan Osborne stole their money from them and also didn't credit their writing.
