To Sir, with Love by Lulu is featured in Journey, the twenty-second and final episode of Season One. It is sung by the New Directions, with solos from Artie, Finn, Kurt, Mercedes, Rachel, Santana, and Tina.
As the members of New Directions are still coming to terms with the fact that the club has been cancelled, this song is sung as a thank you to Mr. Schuester, showing that they can all change from their previous ways. Everyone was very emotional during the performance, either crying or very close to tears. Sue is seen watching the performance at the entrance of the April Rhodes Civic Pavilion.

Tina with Artie:
The time has come
For closing books
And long last looks must end
Mercedes with Finn:
And as I leave
I know that I am leaving my best friend
A friend who taught me right from wrong
And weak from strong
That’s a lot to learn
What can I give you in return?
Rachel with Artie and New Directions:
(Rachel: Oh) If you wanted the moon, I would
(Santana: Try) Try and make a start, but I
Rachel with Artie, Santana and New Directions:
Would rather you let me give my heart
To sir, with love
