The reprise of "Let's Play a Love Scene" when Nick finally gets it.
You were the honest friend, I was the great pretender/I hid my feelings until the end/But now I want to say what it means to me/How things will never be the same without you . . .
"Bring On Tomorrow" is part-this, part-Tear Jerker, and part CMOA.
Tyrone's message on the board - "I WILL READ."
"These Are My Children". Full stop. The entire song, which proves how devoted Miss Sherman is to her students.
From the series version, there's the song "Starmaker" from the 1st season finale "A Special Place" as sung to the character of Mr. Gregory Crandall (played by Michael Thoma). Also a Real Life example, as Thoma was leaving after a diagnosis of pancreatic cancer, and ended up dying a few months laternote (the reason for the departure of his character was due to cutbacks, with the character being mentioned off-screen early in Season 2 and being a case of the character (briefly) outliving the actor before his character died from a heart attack)
