Straight No Chaser (SNC) is the name of two related but separate a cappella men's singing groups. The Indiana University group 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," gained widespread popularity and subsequently led to a five-album record deal with Atlantic Records in 2008. The YouTube video has been viewed more than 13 million times.
