“Joanna” is a breezy, soulful 1983 R&B and pop track that served as a massive hit single from the group’s album In the Heart. The song features an incredibly catchy, mid-tempo groove driven by a walking bassline, jazzy guitar chords, and a bright, finger-snapping rhythm that echoes vintage doo-wop styles. The arrangement is perfectly polished, balancing a retro-soul romantic sensibility with the smooth electronic pop production of the early 1980s.

Lyrically, the song is an affectionate, warm, and highly nostalgic tribute to a sweet, captivating woman who has completely won the narrator’s heart. The band shines through their light, breezy vocal delivery, trading lines with an incredibly tight, soulful backing harmony group that continuously chants her name. The song’s cheerful melody, easy-listening tempo, and infectious pop-funk sweetness turned it into an immediate radio favorite and a major international chart success.
