Who invented the ABC Alphabet song?

The familiar "alphabet song" was originally copyrighted by Charles Bradlee in 1935, however he only created the lyrics. The tune is the same used for "Twinkle, Twinkle, Little Star," and is originally from a French folk song called "Ah! Vou dirai-je, Maman." Some have mistakenly attributed this song to Mozart because he produced several themes on the original folk song.
