We're counting down the 12 Days of Christmas with daily mini-episodes spotlighting a classic holiday song and featuring an interview with the writer. On this seventh day of Christmas, we explore "Mary Did You Know?" with co-writer Mark Lowry. The gospel music legend tells us all about the holiday standard that's since been covered by Pentatonix, Natalie Cole, CeeLo Green, Mary J. Blige, Kenny Rogers, Reba McEntire, and many others.
