Proof Jazz Was Dead by 1939
The Wizard of Oz was released in 1939. Nothing else happened that year, nothing else mattered. (Unless you count the start of WWII, of course.) The song and dance number “The Jitterbug” was cut from the film before its release, proving that jazz, as an art form, was indeed dead by 1939.
You can read the slightly offensive lyrics here. You can also download Wizard of Oz ring tones for your cell phone. Don’t everyone do it once, though - we don’t want to crash their server.
