"Now You Has Jazz" is a song written by Cole Porter for the 1956 film High Society in which it was introduced by Bing Crosby and Louis Armstrong.
The song describes what instruments are needed to create jazz.
Sol C. Siegel, the producer of High Society, paid Cole Porter $250,000 for his first film score in eight years.
When Porter learned that Louis Armstrong was going to appear in the film, he decided he had to write a jazz song.
To help with his research, he called Fred Astaire and suggested they attend a Jazz at the Philharmonic concert.
