Of course, the age-old tradition that a star must appear even if he or she is practically dying is an excellent one, but it can be carried too far. I one played a performance of The Knight of the Burning Pestle with a temperature of 103 and gave sixteen members of the company mumps, thereby closing the play and throwing everybody out of work. There may be a moral lurking somewhere in this, but I cannot for the life of me discover what it is.
