VIDEO: Darren Criss Sings 'Hey, Soul Sister' on 'Glee'
OMG, I love Darren Criss. In the words of Train (and now, the Dalton Academy Warblers), "Watching you is the only drug I need."

After wowing us with Katy Perry's "Teenage Dream" and making it the No. 1 Glee song in the history of ever (it scored the highest first-week sales of any Glee song on iTunes and hit No. 1 on the Billboard chart, people!), Blaine and the adorable (though possibly dance-challenged) Dalton Academy Warblers -- which now includes Kurt -- are doing it again with Train's "Hey, Soul Sister."

Check out the full-version of Blaine and the boys singing "Hey, Soul Sister" from the Nov. 30 episode of Glee, "Special Education":

Love that the Glee kids are there cheering for the little Kurt that could. And I find it adorable (though, obviously out of character) that Rachel's playing stage mom and telling a visibly nervous Kurt to smile on stage. So with all his former co-Glee clubbers on board the Kurt express, why does Mr. Schuester look like he just swallowed some of his own hair gel? Guess we'll find out tomorrow night!

In the meantime, we're totally happy to have this little ditty to hold us over. Mwah, Blaine/Darren Criss!

What do you guys think of the Warblers' version of "Hey, Soul Sister"? Think it's a contender to give "Teenage Dream" a run for its money? Why do you think Schue looks so appalled? Perhaps upset at the stiff competition? Saddened to see the reality of Kurt having changed schools? Weigh in below!
