One of the group's most powerful singles, this uptempo and brassy dance single was somewhat of a departure from the group's much lighter, pop-oriented sound, with a production set for an uptempo soul sound similar to that of material by fellow Motown groups
Martha and the Vandellas and the
Four Tops. The lyrics tell of how the narrator has been "bitten by the love bug" and no matter what she does, she can't "scratch it" (the itch created by the bite of the love bug). Lead singer
Diana Ross' bandmates
Florence Ballard and
Mary Wilson accompany Ross, as she sings about her lover's grasp on her heart. The
girl group performed the hit live on
CBS variety program The Ed Sullivan Show on Sunday, May 1, 1966. ==Reception==
