'Glee': Hear the New Directions' haunting cover of 'Pure Imagination' -- EXCLUSIVE

Last week’s episode of Glee definitely tugged at the heart strings, particularly the crowning of Kurt as Prom Queen and Blaine asking Kurt to dance. (My eyes are welling up just thinking about it again!)

Now, I’m told that next Tuesday’s installment, ominously titled “Funeral,” is one of Glee‘s most emotional hours to date. Uh oh.

Clearly something intense happens based on this cover of “Pure Imagination,” which EW is exclusively premiering today. New Directions puts their own spin on the track, originally sung in the 1971 classic Will Wonka & the Chocolate Factory, for the episode which has been rumored to feature the death of someone or something. Listen below to the haunting version:

“Pure Imagination” is just one of the songs featured on Glee: The Music, Vol. 6, which drops on May 23. To hear more music from “Funeral,” go to gleethemusic.com.
