The 1993 National Show Choir Championship was a competition in which show choirs all across America competed to become the National Champion.
The only seen group, The Singsations, coached by Lillian Adler, and with Will among the club's members, performed That's the Way (I Like It)/(Shake, Shake, Shake) Shake Your Booty, both songs by KC and the Sunshine Band. The Singsations got first place.
The scene where the The Singsations performs the disco mash-up is included in the Pilot first, and later in Saturday Night Glee-ver when Will tells New Directions that his Glee Club won Nationals with a disco mash-up.
