余先生在1932年录了四张唱片,由朱家夔先生操琴。那时余先生大病初愈,嗓音失润,调门也较低。当时长城公司与他接洽,约定以壹千银元一面高于别人的价格请他灌片,余先生同意灌唱片,但时间要由他自己定,哪一天感到嗓子可以就灌录。当时的录音师是一位德国专家,他准备灌完唱片即回? Mr. Yu recorded four albums in 1932 and was trained by Mr. Zhu Jiali. At that time, Mr. Yu was recovering from a serious illness. His voice was lost and his tone was lowered. At that time, the Great Wall Company contacted him and agreed to ask him to pay a piece of silver at a price higher than that of others. Mr Yu agreed to record the record, but his time would have to be set by himself and his throat could be recorded one day. The sound engineer at the time was a German expert who prepared to finish recording the record.
