Country music superstar Morgan Wallen appeared anxious to leave Studio 8H on Saturday, storming off the set of "Saturday Night Live" before the credits finished rolling. Episodes of "SNL" end with the entire cast and guest stars standing on the main stage of the studio and waving to the audience.

Country star Morgan Wallen was brought on Saturday Night Live because he is popular. That makes sense. His appearances help bring eyes to the show and potential new listeners to Wallen. However, some of the best performances ever on SNL are those from musical artists who are not household names.
