On the evening of the performance, three conductors appeared on stage, and Pan himself walked straight up on to the stage from among the audience as the mysterious fourth conductor. Because the piece was written in an open format, the number of conductors, the instruments and the sections chosen to be played could all be adjusted spontaneously, providing infinite scope for variation and interest.
演出當晚台上用了三個指揮，而他就是那位神秘的第四者，直接由台下走到台上；同時，由於這首曲子是採用開放的形式寫成，指揮人數、樂器、選取演出的樂段都可即興調配，因而產生無數的變化和趣味。
