"Istanbul (Not Constantinople)" is a 1953 novelty song, with lyrics by Jimmy Kennedy and music by Nat Simon...
The lyrics humorously refer to the official renaming of the city of Constantinople to Istanbul. The song's original release, performed by The Four Lads, was certified as a gold record. Numerous cover versions have been recorded over the years, most famously a 1990 version by They Might Be Giants.
