Paranoid and Masters Of Reality were in heavy heavy rotation on my turntable when I was 13-14 (but then, so was Bloodrock......); I lost interest in that flavor of music about then though.
But, as a friend of mine once said, "The termination of personal timespan is always a bummer". I second Joey's thoughts on Sharon, Aimee, Kelly & Jack.
And we will never see another rolled from the same makin's as John Michael Osbourne.
Peter (who will add that as short a time as I was into them, those albums were played a lot; the same could not be said for Led Zeppelin IV.........
