The Staples' first album produced by 
Al Bell and recorded in Muscle Shoals hit the winning formula. Other changes saw 
Pervis Staples departing just before the album was recorded and being replaced by sister 
Yvonne Staples. Everything was now in place for the Staples' golden years. Three songs, "Heavy Makes You Happy," "Love Is Plentiful," and "You've Got to Earn It," all charted. ~ Rob Bowman
