Glee's back with Grease theme!

Actually I hate when they started to sing a song from classic or broadway songs, because I don't know them.  It makes my choice of favorite Glee cover more difficult hehehehe. I have to get used to it :p

For this episode, I used to pick Marley and Wade's song, Blow Me (One Last Kiss), but Kitty and Jake amazed me with their atlethic dance. They can sing and dance, what a perfect combo! :D
