Perhaps Andrew Lloyd Webber's best loved musical returns to Berlin. Based on <em>Old Possum's Book of Practical Cats</em> by T. S. Eliot, and produced by Cameron Mackintosh, 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. <em>Cats,</em> first performed in 1981<em>, </em>introduced the song standard <em>Memory</em> amongst many others, and has been seen by more than 73 million people around the world.
