Also I want to point out that Rita Moreno is obviously and absolutely dedicated to the music. She demonstrates how steeped she is in musical knowledge and in the knowledge of how to put the magic of a song across. Of course it involves theater — costume, gesture, expression. All right, OK, this is comedy central. But while would-be-successful comedians are cracking wise, as they "should" do perhaps (young or old), the smart ones will recognize that they'd benefit from studying the art and craft of theater from masterful performance like this one of Rita Moreno's.
