In the mid-1920s Miles spent time performing in Paris, before returning to the United States. She suffered a serious illness and retired from the music industry in the 1930s. Not before she recorded "My Man O' War", described by one music journalist as "a composition stuffed with rococo suggestiveness". In the 1940s she returned to New Orleans, where Joe Mares encouraged her to sing again—which she did, but always from in front of, or beside the stage, since she said she had vowed in a prayer not to go on stage again if she recovered from her illness. Miles was based in San Francisco, California, in the early 1950s, then again returned to New Orleans where she recorded with several Dixieland and traditional jazz bands and made regular radio broadcasts, often performing with Bob Scobey or George Lewis.
