The Fox series is also giving viewers a hearty dose of 'West Side Story' songs to go along with the monumental episode.
The 'Glee' cast covers 'A Boy Like That,' 'Tonight,' 'America,' and 'One Hand, One Heart.' Head on over to Wall Street Journal to hear the Warblers cover Billy Joel's 'Uptown Girl.'
Fans will remember this isn't the first time New Directions has tackled 'Tonight.' Back in Season 1, Tina was given the solo, much to Rachel's dismay. However, this time it's all Rachel (Lea Michele) and Blaine (Darren Criss) and they pretty much nail it.
