The cartoon's opening credits originally had the legend "A Vitaphone song cartoon produced by Hugh Harman & Rudolph Ising", then changed to "A Hugh Harman-Rudolph Ising musical cartoon" and eventually to "A Hugh Harman-Rudolph Ising production".
The scenes in which Bosko's mouth fills the screen and he splits into miniature versions of himself were previously done in Bright Lights, an Oswald the Rabbit cartoon that Hugh Harman and Rudolf Ising worked on whilst they were at Disney.
The song "Singing in the Bathtub", sung here by Bosko, was originally introduced in the Warner Bros. feature The Show of Shows.
Theatrically released in the USA with The Song of the Flame.
This film is the first in the "Looney Tunes" series. Honey makes her first appearance. Bosko makes his first appearance in a theatrical film, and his second appearance of any kind. (His first appearance was in a demo reel called Bosko the Talk-Ink Kid, which was never released commercially.)
