Rachel: I've been cheated by you since I don't know when So I've made up my mind, it must come to an end Look at me now, will I ever learn? I don't know how but I suddenly lose control There's a fire within my soul Just one look and I can hear a bell ring One more look and I forget everything, w-o-o-o-oh
Rachel with Santana and Kurt: Mamma mia, here I go again My my, how can I resist you? Mamma mia, does it show again? My my, just how much I've missed you
Kitty with Marley and New Directions: Yes, I've been brokenhearted Blue since the day we parted

Marley: I've been angry and sad about things that you do
Marley with Rachel: I can't count all the times that I've told you we're through
Marley with New Directions: And when you go, when you slam the door I think you know that you won't be away too long You know that I'm not that strong.
Sam with Kitty and New Directions: Just one look and I can hear a bell ring One more look and I forget everything, w-o-o-o-oh
