"Please Mister Postman" by The Marvelettes hit number one on Billboard Magazine's Hot 100 the week of December 11th, 1961. The group was formed by five high school students in the Detroit suburb of Inkster, originally going by the name The Casinyets (short for “Can’t Sing Yet").
"Please Mister Postman” featured lead vocals by Gladys Horton, who passed away earlier this year at the age of 66. It was the biggest hit The Marvelettes would have. The group also scored with classics like "Beechwood 4-5-7-8-9", "Too Many Fish In The Sea", and "Don't Mess With Bill".
"Please Mister Postman" was the first of many number one pop hits for Motown.
