While Davis and Mitchell are the credited songwriters of "You Are My Sunshine", Davis was never known to actually claim authorship, as he bought the song and rights from Paul Rice and put his own name on it, a practice not uncommon in the pre-World War II music business. Some early versions of the song credit the Rice Brothers. Descendants and associates of Oliver Hood, a Georgia musician who collaborated with Rice, claim Hood wrote the song in the early 1930s, first performing it in 1933. According to some accounts, clarinetist Pud Brown was also involved with the Rice Brothers for the song's origin or first arrangement.
