In those early days there were no intermissions. If an audience member wished to use the restroom or smoke a cigarette, they would wait for scenery change. Actors would sing without microphones, just relying on the strength of their voice. For effects, they would use sounds from a record.
當年話劇不像現在有中場休息，觀眾如要上廁所、抽根煙，都是利用換幕空檔；演員說唱不用麥克風，全憑一條亮嗓子，但為了效果，會利用唱片製造音效。
