These are my favorite Glee performances to date:
1. Teenage Dream
2. Poker Face (the video is a little slower than the music)
3. Gives You Hell
4. Toxic
5. Sweet Caroline
6. Sit Down, You’re Rockin’ the Boat – can you tell that Guys and Dolls is my favorite musical?
Did I miss any good ones?

i LOVED teenage dream this week (and the girls’ mash-up!).
i think that my all-time favorite, though, is the one that got me hooked on glee to begin with: don’t stop believin’.

LOVE EM ALL!
Glee is my fave! I like the songs Mr. Scheuster sings… Bust a move was a good one!
