Four nuns have started a band at the Catholic University of America. Sisters Miriam, Louis Marie, Peter Grace and Mary Andre are part of the band Force of Habit, which was started to be a presence on the campus, connect with other students, and share and demonstrate their faith. The band doesn't play religious songs, but tunes like "Unforgettable" and "What a Wonderful World." The group originally started as singing group called Nun of the Above. (Washington Post)
