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 St. Olaf College Choir was established as an outgrowth of the local St. John's Lutheran Church, where Christiansen was organist and the choir was composed, at least partially, of students from the nearby St. Olaf campus.". Is that enough to answer the question?
