Merrie Melodies - One Froggy Evening (1955)

One Froggy Evening is a 1955 animated musical short film written by Michael Maltese and directed by Chuck Jones, with musical direction by Milt Franklyn. The short, partly inspired by a 1944 Cary Grant film entitled Once Upon a Time involving a dancing caterpillar in a small box, marks the debut of Michigan J. Frog. This popular short contained a wide variety of musical entertainment, with songs ranging from "Hello! Ma Baby" and "I'm Just Wild About Harry", two Tin Pan Alley classics, to "Largo al Factotum", Figaro's aria from the opera Il Barbiere di Siviglia. The short was released on December 31 (New Year's Eve), 1955 as part of Warner Bros.' Merrie Melodies series of cartoons.

Production notes
The cartoon has no spoken dialogue or vocals except by the frog. The frog had no name when the cartoon was made, but Chuck Jones later named him Michigan J. Frog after the song "The Michigan Rag", which was written for the cartoon. Jones and his animators studied real-life frogs to achieve the successful transition from an ordinary frog to a high-stepping entertainer. The character became the mascot of The WB television network in the 1990s. In a clip shown in the DVD specials for the Looney Tunes Golden Collection, Jones states that he started calling the character "Michigan Frog" in the 1970s. During an interview with writer Jay Cocks, Jones decided to adopt "J" as the Frog's middle initial, after the interviewer's name.
