Can't get enough of this. I'm guessing if you've never seen the show, the season finale would be an EXCELLENT place to start. It's going to be amazing as made evident in this video. Love the dresses. Love the song. Love Finn and Rachel.
...and for MORE finale goodness, listen to the songs they'll be singing. My favorite is Puck and Santana's rendition of Don't Stop Believing, but I'm also a sucker for Somewhere Over the Rainbow and Bohemian Rhapsody. Seriously. How do people not watch this show?! If you like music, you'll like Glee.
