I want to know the answer to the following question:
Who did the St. Olaf Choir influence?
All the background I'm provided with is that "The success of the ensemble was emulated by other regional conductors, and a rich tradition of a cappella choral music was born in the region at colleges like Concordia College (Moorhead, Minnesota), Augustana College (Rock Island, Illinois), Wartburg College (Waverly, Iowa), Luther College (Decorah, Iowa), Gustavus Adolphus College (St. Peter, Minnesota), Augustana College (Sioux Falls, South Dakota), and Augsburg College (Minneapolis, Minnesota).". Is that enough to answer the question?
Answer: yes
