The Marvelettes

Please Mr. Postman" was the debut single by The Marvelettes for the Tamla (Motown) label, notable as the first Motown song to reach the number-one position on the Billboard Hot 100 pop singles chart. The single achieved this position in late 1961; it hit number-one on the R&B chart as well. "Please Mr. Postman" became a number-one hit again in early 1975, when The Carpenters' cover of the song also reached the top position of the Billboard Hot 100
