Gladys Horton was the original lead singer and co-founder of The Marvelettes, the pioneering girl group who gave Motown it's first #1 Billboard pop hit in 1961 with the single "Please Mr. Postman." The Marvelettes were instrumental in putting Motown on the map, paving the way for all-female vocal groups like The Supremes, The Ronettes, and Martha and the Vandellas. Horton passed away earlier this week at the age of 65 (not 66, as some sources have reported) from complications due to a stroke she suffered last year. In honour of this marvellous Marvelette, this week's sunday song's is dedicated to Gladys Horton and her sassy, upbeat vocals.
