MacArthur Park was a long ballad written by Jimmy Webb, and brought to number 2 in 1968 by Richard Harris. In 1978, Donna Summer took her disco version to number one. MacArthur Park broke out of the three-minute song format, being played on the radio despite much longer lengths. The uncut Richard Harris version was 7 minutes 41 seconds. The uncut version by The Four Tops was 6 minutes 34 seconds. Donna Summer had various disco versions. Her single version was just under 4 minutes.
Two famous versions, Muck-Arty Park by Soupy Sales and Jurassic Park by Weird Al Yankovic, were parodies.
