[1] His assistant, Chuck Chapman, kept the studio running until 1975, then moved into the Cavern Sound facility in Independence, Missouri, for two more years operating as Cavern/Damon.
[3] Damon used musicians and singers who were not members of the American Federation of Musicians labor union to make recordings during the ban on Union recordings ordered by James Petrillo.
In May 1948, the singing duo of Jon and Sondra Steele released "My Happiness" on Damon Records, a fact that was acknowledged on sheet music promoting the song.
The Al Trace Orchestra recorded for major labels in the 1940s in addition to Damon.
Trace was a writer on several popular songs, including "If I'd Known You Were Coming I'd Have Baked a Cake."
