Istanbul (Not Constantinople)
From Wikipedia, the free encyclopedia

"Istanbul (Not Constantinople)" is a swing-style song, with lyrics by Jimmy Kennedy and music by Nat Simon. The tune is similar to and possibly based on the music for "Puttin' on the Ritz", written by Irving Berlin in 1929. [1]

It was originally recorded by The Four Lads on August 12, 1953. This recording was released by Columbia Records as catalog number 40082. It first reached the Billboard magazine charts on October 24, 1953, and it peaked at #10. [2]

The lyrics remind the listener of the change of the name of the city Constantinople to the Turkish name of Istanbul, also mentioning the fact that New York City was originally named New Amsterdam.
