Please Mr. Postman by The Marvelettes
Released in the summer of 1961, Please Mr. Postman was an instant mega-hit. It was the first No. 1 for any Motown artist, and one of the biggest ever hits recorded by a group of women of color, later being covered by such esteemed artists as The Beatles and The Carpenters.

The Marvelettes helped to popularize a lot of elements of girl groups that would become mainstays of the musical world like cute, matching outfits and catchy backing vocals. The song is regarded as quite cheerful, but it’s really rather tragic, speaking of women desperate for news from her lover, who is believed to be off at war.
