"Take the 'A' Train" (1923) is a jazz standard by Billy Strayhorn that was the signature tune of the Duke Ellington orchestra.
The lyrics used by the Ellington band were added by Joya Sherrill, who was 17 at the time (1944). She made up the words at her home in Detroit, while the song played on the radio.
===========================

You must take the "A" train
To go to Sugar Hill way up in Harlem
If you miss the "A" train
You'll find you missed the quickest way to Harlem

Hurry, get on, now it's coming
Listen to those rails a-thrumming
All aboard, get on the "A" train
Soon you will be on Sugar Hill in Harlem
