Ella Mae Morse (September 12, 1924 – October 16, 1999)[1] was an American singer of popular music whose 1940s and 1950s recordings mixing jazz, blues, and country styles influenced the development of rock and roll.

She also originated the wartime hit "Milkman, Keep Those Bottles Quiet",[5] which was later popularized by Nancy Walker in the 1944 film Broadway Rhythm.

[8][9] Her biggest solo success was "Blacksmith Blues" in 1952, which sold over one million copies, and was awarded a gold disc.

[12] Morse ceased recording in 1957, but continued performing until the early 1990s, under the new management of Alan Eichler,[13] performing at such clubs as Michael's Pub in New York,[14] Ye Little Club in Beverly Hills, the Hollywood Roosevelt Hotel's Cinegrill and the Vine St. Bar and Grill.

She appeared regularly at Disneyland for several years with the Ray McKinley Orchestra, and did a successful tour of Australia shortly before her final illness.

As Morse's musical style blended jazz, blues, and country, she has sometimes been called the first rock 'n' roll singer.
