My dad was the first full time band director at Sherman High School in Sherman, TX in 1939-41. He even wrote the school song and fight song, which is now used only as the school song. I taped him in 1987 giving a talk at the band banquet at the end of the year. He had recorded a tape of his band and what they sounded like in 1940!
My dad only taught band for two years because music had not been his major, but here is what a Texas band sounded like in 1940. We have come a long way with our music education programs!
