Life is full of little surprises, never did I expect to be teaching any one of my sons the guitar riff from the Sabs 1971 "Iron Man". A truly awful piece of work that even then (I recall there was a very short time when handling the first Black Sabbath album was cool) was disliked by everybody except complete meat heads. However time and marketing are strange things and now that leaden, 6th form, primitive riff has re-emerged and become associated with what looks like a very good film. My 13 year old likes the basic riff but not the rest of the song so at least he has some good taste. Iron Man should be last of the big Marvel movies, I can't imagine Dr Strange easily making it to the big screen and if he did what music would fit - the Cure? The back catalogues continue to be pillaged and our imaginations and memories are put firmly back into some desolate and dark place.
