I picked up We Sold Our Soul For Rock N Roll Vol. 1 a while ago and after finally getting a chance to listen to it, it became apparent to me that early Sabbath definitely had a bluesy side to it. If you need proof then listen to The Wizard. Now I have images of Ozzy playing a harmonica running through my head. I can remember seeing the video for "Bark At The Moon" way back in '83 on a long gone show called "Radio 1990", it had little facts rolling while the vid played and it said that Ozzy tripped on LSD every day for almost two years.
