[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
Mmm, 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, oh whoa

[RACHEL with KURT & SANTANA]
Mamma mia, here I go again
My, my, how can I resist ya?
Mamma mia, does it show again?
My, my, just how much I've missed ya

[KITTY with MARLEY]
Yes, I've been brokenhearted
Blue since the day we parted

[BLAINE with MARLEY & NEW DIRECTIONS]
Why, why did I ever let you go?
Mamma mia, now I really know
My, my, I could never let you go

[MARLEY]
I've been angry and sad
About things that you do
[MARLEY with KITTY]
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 MARLEY & NEW DIRECTIONS]
Just one look and I can hear a bell ring
One more look and I forget everything, oh whoa

[BLAINE & RACHEL with KURT, SANTANA, & NEW DIRECTIONS]
Mamma mia, here I go again
My, my, how can I resist ya?
Mamma mia, does it show again?
My, my, just how much I've missed ya

[RACHEL with SANTANA]
Yes, I've been brokenhearted
Blue since the day we parted

[BLAINE & RACHEL with KURT, SANTANA, & NEW DIRECTIONS]
Why, why did I ever let you go?
Mamma mia, even if I said
Bye, bye, leave me now or never
Mamma mia, it's a game we play
Bye, bye, doesn't mean forever
Mamma mia, here I go again
My, my, how can I resist ya?
Mamma mia, does it show again?
My, my, just how much I've missed ya

[MARLEY & UNIQUE with NEW DIRECTIONS]
Yes, I've been brokenhearted
Blue since the day we parted

[BLAINE & MARLEY with NEW DIRECTIONS, (UNIQUE), {with UNIQUE}]
Why, why (Why)
{Did I ever let you go}
Mamma mia (Mamma Mia)
Now I really know
{My, my}
I could never let you go (Oh!)

[NEW DIRECTIONS]
Whoa oh oh oh
Whoa oh oh oh

[BLAINE & RACHEL with NEW DIRECTIONS]
Mamma Mia!
