During a choatic concert one evening, Hector Berlioz turned to conduct his own Symphonie Fantastique and was dismayed to find that most of the orchestra had gone home.

It was a rule of the Theatre Italien that musicians not be required to work past midnight.

[Though the audience clamored for the remaining musicians (five violins, two violas, four cellos and a trombone) to play the piece anyway, Berlioz reluctantly declined. "It is not my fault," he sheepishly remarked. "The orchestra has disappeared."]
