GLEE - Full Performance of ''The First Time Ever I Saw Your Face” from “Yes/No”

The First Time Ever I Saw Your Face by Roberta Flack is featured in Yes/No, the tenth episode of Season Three. It is sung by Mercedes, Rachel, Santana and Tina.
As part of the Glee Club's assignment to find the perfect song for Will's proposal to Emma, Mercedes, Rachel, Santana and Tina perform a quartet rendition of this song. Right before the performance begins, the girls ask Will to think back to the first time he ever saw Emma's face. During the song, each of the girls has a flashback to an important moment they shared with their respective loved ones. Rachel has a flashback to when she and Finn locked eyes for the first time in the hallway, Santana has a flashback to when she and Brittany smiled at each other in the girls locker room, Tina remembers the time she and Mike shared a romantic picnic together and Mercedes, although currently dating Shane, has a flashback to when she and Sam first saw each other near the football field.
It is apparent that Mercedes felt guilty about thinking about Sam during the song, because at the end of the song she emotionally runs out of the auditorium and into the nearby bathroom. Tina, Santana, and Rachel find her and talk to her about the situation with the two boys.
Lyrics:
Rachel:
The first time ever I saw your face
I thought the sun rose in your eyes
Tina:
And the moon and the stars were the gifts you gave
Tina with Mercedes, Rachel, and Santana:
To the dark, (to the dark) and the end of the skies
Mercedes, Rachel, and Santana:
My love
Mercedes:
And the first time ever I kissed your mouth
I felt the earth move in my hand
Like the trembling heart
Of a captive bird
Tina with Mercedes, Rachel, and Santana:
That was there (that was there) at my command
My love
Santana:
And the first time ever I lay with you
I felt your heart so close to mine
Mercedes:
And I knew our joy would fill the earth
Mercedes with Rachel, Santana, and Tina:
And last (and last) 'til the end of time
My love
Rachel:
And the first time ever I saw
Tina with Mercedes, Rachel, and Santana:
Your face
Mercedes with Rachel, Santana, and Tina:
Your face
Santana with Mercedes, Rachel, and Tina:
Your face
Rachel with Mercedes, Santana, and Tina:
Your face
