Interwoven with "Dancing Mad" are the opening theme "Omen", during the first and last movements, as well as portions of "Catastrophe" in the first movement; Kefka's theme, during the third and last movements; and Kefka's unmistakable laugh, after the closing section of the last movement before it repeats itself. At nearly eighteen minutes in length in its original version (with each movement played through twice), "Dancing Mad" is the longest track recorded as a boss theme in the series. Some later remixes shortened the overall length to approximately ten to twelve minutes long.
