Here is the description of these records from the original WATCHTOWER MAGAZINE of April 1, 1917:
"Some time before his death Brother Russell arranged to have a set of fifty phonograph records made of the choicest old fireside tunes, many from the MILLENNIAL DAWN HYMNAL. On the reverse side a short talk by himself explaining the doctrinal points of the hymn. It was his thought that a large number of these should be prepared and sold to the five and ten cent stores, expecting that they would have a wide sale and awaken in the minds of the righteously disposed a desire for spiritual things. Brother Russell was always alive to use every channel possible to send out the light and truth and each of these talks is a gem itself.
"Friends who knew of his plan urged him to have the Bible Talks recorded in his own voice. This he did; but owing to his rapidly declining strength, it was later found that his voice was not strong enough to make a good record.
"Brother Russell then thought to have them re-recorded by the gentleman who made the CREATION DRAMA records so great a success. Our Pastor's death, however, upset these plans.
"The brethren interested in the Angelophone Company, believing that Brother Russell's friends would be very glad to have even so weak a record of his voice, continued to carry out his instructions so far as possible. Some of the friends who purchased the records, not understanding why Brother Russell's voice was so weak and low, and thinking the manufacturer at fault, complained. Others who purchased the records write that they are so well pleased that they would not be without them for a thousand dollars, if they could not secure another set. We believe that many more will take this same view when they understand all the circumstances."
