Straight No Chaser (SNC) is the name of two related but separate
a cappella men's singing groups. The
Indiana University amateur college group now known as "Indiana University's Straight No Chaser" is composed of 10 to 12 undergraduate men whose lineup changes every year. The professional group, known simply as Straight No Chaser, is composed of former members, mostly original members, of the college group. In 2006, a 1998 video of "The 12 Days of Christmas," went viral and subsequently led to a five-album record deal with Atlantic Records in 2008. The YouTube video has been viewed by more than 11 million people, including the chairman and president of Atlantic Records, Craig Kallman, who arranged the five-album recording deal.
