The only Format Films-produced Road Runner short with a scene-specific score by William Lava. The other ten used a handful of pre-recorded melodies that were recycled over and over.
The first of eleven Road Runner shorts outsourced to Format Films, as opposed to being animated by DePatie-Freleng Enterprises as usual.
The first Road Runner short without any involvement of Chuck Jones, who also got fired from Warner Bros. for signing the contact so that he and his team moved on to MGM to create the Tom and Jerry shorts from 1963 to 1967.
The first Road Runner cartoon produced by Herbert Klynn (who was left uncredited) instead of David H. DePatie and Friz Freleng, which weren't belong in the eleven Road Runner shorts out of fourteen.
The title is a play on the film "Hush, Hush, Sweet Charlotte" (1964).
