Some History of WSM, Nashville
Richard L. White provided the following early information on WSM, consulting the Nashville Tennessean, Nashville Banner, and National Life and Accident Insurance Company archives over a period of 20 years.
The first broadcast of the WSM Barn Dance only featured an 80 year old fiddler by the name of Uncle Jimmy Thompson, a Civil War veteran, and lasted one hour. This was due to the fact that that hour needed to be filled by a vacancy that came up from 8 - 9 pm, and the telegrams poured in for his fiddling. The WSM Barn Dance did not become a slated regular show until December of 1925, although there was always fiddling in that time slot until January. Dr. Humphrey Bate was the second performer on the program, appearing for his first time on December 12. On Saturday night, January 2, 1926, the WSM Barn Dance began to be a loosely formatted live program with a two-three hour show, depending on other programming.
WSM went dark on December 4, 1926 and did not come back on the air again until January 8, 1927, as the transmitter was being replaced during that entire period. Telegrams poured in to WSM on Saturday night with the last broadcast on 1000 watts and even more telegrams came in to WSM on January 8 with the new 5000-watt transmitter. WSM was broadcasting on Monday-Wednesday-Saturday and alternating Sunday nights in the first year as they shared the same broadcast location with WOAN out of Lawrenceburg, TN. They broadcast on 1060 AM until 1929, and then they were moved by the FCC to 650 AM as one of the newly assigned clear channels.
