 Cut Song: In the stage version of Cats on Broadway, London and  National Tours, during "Gus: The Theatre Cat" song, midway through  the song, usually is a lavish production number known as  "Growltigers Last Stand/The Ballad of Billy Mccaw". It is a memory  of a performance that Gus was in in his younger performing days.  Usually there is also a big set change to a pirate ship.
