Lets hope the choice was accidental;
"In 1939 Rice sold the rights to the song to Charlie Mitchell and Jimmie Davis (a common practice in the music business of that era).
Jimmie Davis was a well-known country singer and politician. He recorded “You Are My Sunshine” in 1940, and the song propelled him to elected office in 1944 and again in 1960. He used it as his campaign theme, often singing it while riding a horse called Sunshine.
In 1960 Jimmie Davis was elected Louisiana governor on a segregationist ticket."
While it's not necessarily an anti-civil rights anthem as black performers recorded it later.
It's probably not a random choice in your town Hall.
