On the topic of the “Moody Blue” album sleeve there’s a story in one of Sean Shaver’s books (“Photographing The King” if my memory is correct) saying that Elvis wanted a picture of himself playing the piano on stage as the album’s cover shot. I don’t know how much truth there is to this story, but Sean Shaver did take some photos of a slimmed down Elvis playing piano in the king of spades suit, during the December 1976 tour, and one of these photos would have made a good cover shot for the album.
