This session featuring Robertson on vocal was led by Hal Davis, about whom I have no further information. Dick Robertson was one of the busiest band and studio singers from the late '20s through the early '40s, as well as a composer. He recorded under a lot of pseudonyms and worked with Eubie Blake, Duke Ellington, The Mills Blue Rhythm Band, Benny Goodman, Andy Kirk and many others. Robertson also cut a variety of sides as a leader, organizing ensembles dubbed the Dick Robertson Orchestra with the type of studio musicians who kept as busy as he did during this era. This excellent record was made in 1935.
