Cats is an amazing world-wide loving musical with almost no plot-line. It was the longest running Broadway Musical, and is still yet to be defeated. I hope that someday it will return to Broadway someday.
The Musical starts with the Overtour, in the movie version it has a bunch of signature Cats eyes coming towards yo, but in the musical version a bunch of lights move around, some seizure inducing stuff as well move around the stage and the Cats come on with glowing eyes and then disappear right before the end.
