Merrily We Roll Along (song)

"Merrily We Roll Along" is a song written by Charlie Tobias, Murray Mencher, and Eddie Cantor in 1935, and used in the Merrie Melodies cartoon Billboard Frolics that same year. It is best known as the theme of Warner Bros.' Merrie Melodies cartoon series.

In the 1970s, it was adopted by WGN as the theme music for The Ray Rayner Show, which featured Warner Bros. cartoons. In 1995, it was used as the closing theme of Sylvester and Tweety Mysteries.

The song shares a title with the 1934 play Merrily We Roll Along by George S. Kaufman and Moss Hart, but is unrelated to it.
