The National Orchestra Service, Inc. (NOS), was the most important booking and management agency for territory bands across the Great Plains and other regions from the early 1930s through 1960.
The company's reputation as the premier booking agent in that genre helped them dominate their industry for almost 20 years.
Bands that NOS represented were typically smaller than the Glenn Miller-type orchestras, usually featuring about 12 pieces, sometimes 15; though ensemble sizes tended to wax and wane with the economy.
[2] Serl Frank Hutton was its founder and sole proprietor until 1952, when Lee Williams joined as a partner.
[5] In August 1943, Lee Williams was the only band working for National Orchestra Service due to war rationing (gasoline, tires, and the like) and shortage of musicians (the draft).
