Glee‘s Darren Criss joins Matthew Morrison on an “impromteau” version of Matthew’s first solo single “Summer Rain” and then the pair crank out a great mash-up of “Great Balls of Fire/When I Saw Her Standing There.”
After singing the first song, Darren exclaims “I lied. I followed you here. I know all your songs, I’m like the biggest fan.”
After you’ve listened to the songs, make sure to check out our gallery of adorable Darren Criss photos.
