 The 1993 re-releases of "The Madcap Laughs" and "Opel" contain alternate versions of "Octopus" and "Clowns and Jugglers" respectively, as bonus tracks.The album's title came about as a result of co-producer David Gilmour mishearing a line from this song (""Well, the mad cat laughed at the man on the border..."" - although the word "madcap" does figure in another of the song's lyrics, ""To a madcap galloping chase"").
