Tyler Golden/FOX
Kurt (Chris Colfer) and Blaine (Darren Criss) reminisce in the special two-hour "2009/Dreams Come True" series finale episode of "Glee" on March 20 2015 on FOX. 

Is "Daydream Believer" Kurt and Blaine's final duet together?

It's certainly one of them, and Billboard can now give you an exclusive listen to the Darren Criss/Chris Colfer performance of The Monkees' hit from Glee's finale, which airs this Friday (March 20).

Glee's two-hour final episode, "2009/Dreams Come True," will involve flashbacks and flashforwards. The program will go into the future to show what is in store for each of McKinley High's treasured alums. Will Rachel go to Broadway? Will Kurt and Blaine have a kid? Will Fondue for Two finally break the Internet? So many questions!

Many of the actors were on Ellen last week, where they told the host that the finale will also involve a tribute to Finn/Cory Monteith, as well as plenty of tears.
