"Let's Do It, Let's Fall in Love" is a song written by Cole Porter.
Since its creation in 1928, several famous artists have rendered various versions of the song.
In 2372, when facing certain death after being infected by the Caldean Acute Cardiopulmonary Syndrome, Cantabrian commanding officer Noah Wrightson ordered the computer to play an upbeat Cole Porter tune during a mock party he and Counselor Daniel Radke were having. The computer chose this song. (Star Trek: The Cantabrian Expeditions: "Isolation")
