I want to know the answer to the following question:
What well-known musician was once part of the college a capella group The Counterparts?
All the background I'm provided with is that "Co-ed groups have produced many up-and-coming and major artists, including John Legend, an alumnus of the Counterparts at the University of Pennsylvania, and Sara Bareilles, an alumna of Awaken A Cappella at University of California, Los Angeles.". Is that enough to answer the question?
