WATCH: Blaine, Brittany, and Mike Catch Disco Fever on 'Glee'

By: Michael Matson

Glee's April 17th episode is devoted entirely to the Saturday Night Fever soundtrack, which was one of the top five best selling albums of the 1970s. And even though the fictional students at McKinley High were all born in the '90s, Blaine Anderson, Brittany S. Pierce, and Mike Chang each come down with a severe case of disco fever.

Go below to check a clip of Darren Criss, Heather Morris, and Harry Shum Jr. performing the Bee Gees "You Should Be Dancing,"  which features Criss jumping in the air and doing the splits.
