CATS is a musical composed by Andrew Lloyd Webber, based on Old Possum's Book of Practical Cats by T. S. Eliot. The musical tells the story of a tribe of cats called the Jellicles and the night they make what is known as "the Jellicle choice" and decide which cat will ascend to the Heaviside Layer and come back to a new life. Cats introduced the song standard "Memory". The first performance of Cats was in 1981.
As of 2016, Cats is the fourth-longest-running show in Broadway history. It has been performed around the world many times and has been translated into more than 20 languages.
