[Mandy Moore]
Ninety miles outside Chicago,
Can't stop driving, I don't know why
So many questions, I need an answer
Two years later you're still on my mind

[Jonathan Foreman]
Whatever happened to Amelia Earhart?
Who holds the stars up in the sky?
Is true love just once in a lifetime?
[Both] Did the captain of the titanic cry?

[Chorus]
[Both] Someday we'll know
[Mandy] If love can move a mountain
[Both] Someday we'll know
[Jonathan] Why the sky is blue
[Both] Someday we'll know
[Both] Why I wasn't meant for you

[Mandy] Does anybody know the way to Atlantis?
[Jonathan] Or what the wind says when she cries?
[Mandy] I'm speeding by the place that I met you
[Both] For the ninety-seventh time [tonight]

[Chorus]
[Both] Someday we'll know
[Mandy] If love can move a mountain
[Both] Someday we'll know
[Jonathan] Why the sky is blue
[Both] Someday we'll know
[Both] Why I wasn't meant for you

Yeah, yeah, yeah, yeah

[Both] Someday we'll know
[Jonathan] Why Samson loved Delilah
[Both] One day I'll go
[Mandy] Dancing on the moon
[Both] Someday you'll know
[Both] That I was the one for you

[Mandy] I bought a ticket to the end of the rainbow
[Jonathan] Watch the stars crash in the sea
[Mandy] If I could ask God just one question
[Both] Why aren't you here with me [tonight?]

[Chorus]
[Both] Someday we'll know
[Jonathan] If love can move a mountain
[Both] Someday we'll know
[Mandy] Why the sky is blue
[Both] Someday we'll know
[Both] Why I wasn't meant for you

Yeah, yeah, yeah, yeah

[Both]Someday we'll know
[Jonathan] Why Samson loved Delilah
[Both] One day I'll go
[Mandy] Dancing on the moon
[Both] Someday you'll know
[Both] That I was the one for you
