Quote from : Old Possum's Book of Practical Cats Book

Gus is the Cat at the Theatre Door. His name, as I ought to have told you before, Is really Asparagus. That's such a fuss To pronounce, that we usually call him just Gus. His coat's very shabby, he's thin as a rake, And he suffers from palsy that makes his paw shake. Yet he was, in his youth, quite the smartest of Cats — But no longer a terror to mice or to rats. For he isn't the Cat that he was in his prime; Though his name was quite famous, he says, in his time. And whenever he joins his friends at their club (which takes place at the back of the neighbouring pub) He loves to regale them, if someone else pays, With anecdotes drawn from his palmiest days. For he once was a Star of the highest degree — He has acted with Irving, he's acted with Tree. And he likes to relate his success on the Halls, Where the Gallery once gave him seven cat-calls. But his grandest creation, as he loves to tell, Was Firefrorefiddle, the Fiend of the Fell.
