As Meddle was the necessary stepping stone for Pink Floyd's making of The Dark Side of the Moon, Sheer Heart Attack was the necessary stepping stone for Queen's making of A Night at the Opera. We work in a Bob Felder/Queen Elizabeth reference, a Chris Farley Heart Attack reference, a heart attack fries reference from Curb your enthusiasm, and Mr. Bean leaving a guy who's having a heart attack on a public curb. All very tasteless, all very fun. Enjoy!!
