"Love and Happiness" is an equation that Al Green spent his career trying to solve. He recorded it in 1972 as a slow-burning meditation on whether love and happiness are the same thing or just neighbors who borrow sugar from each other. The song does not settle the question. It keeps turning it over, examining it from different angles. The call-and-response with his voice and the guitar mimics the internal dialogue of someone trying to figure out whether what he feels is real.
