Be Yourself Tonight is the fourth studio album by British pop duo Eurythmics, released on 29 April 1985 by RCA Records. It spawned four singles – "Would I Lie to You?", "There Must Be an Angel (Playing with My Heart)", "Sisters Are Doin' It for Themselves" (a duet with Aretha Franklin) and "It's Alright (Baby's Coming Back)". The album has been described as their most commercially successful album, and has been pitched as "one of the greatest pop and rock albums of the 1980s". A notable departure from both the musical composition and image of their previous albums, Be Yourself Tonight was widely regarded as an example of their finest work due to their continued "innovation" of their music.
