One Indescribable Instant (reprise) lyrics

[TUCKER]
In one indescribable instant
The whole world falls away
In one indescribable instant
You'll know just what to say

In one indescribable instant
Your heart will speak the truth
'Cause in that one indescribable
Magical, mystical

[TUCKER AND REBECCA]
Endless, incredible
Instant

[TUCKER]
I'll try to match you

[REBECCA]
No, I was harmonizing

[TUCKER]
Oh, okay, I'll go down a third

{REBECCA]
You know what, you just finish it
[TUCKER]
The only words you'll need are "I love you."
