I want to know the answer to the following question:
How many singers are typically in the choirs?
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?
Answer: no
