Lee Morse was a popular singer of the 1920s and early 1930s. She is best remembered today for the backing bands that were assembled for her recording sessions under the name of the Bluegrass Boys. The bands featured many of the best White jazz musicians of the 1920s. Presumably the band was called the Bluegrass Boys to make it sound like they were from the South (Kentucky is called the Bluegrass state). Lee Morse's family had Southern roots but she grew up in Oregon and Idaho, but few if any of the excellent Jazz musicians who played on these records were from the South. The band's music had nothing to do with the string band style of music that arose in the 1940s called Bluegrass.
