If I Could Take That Moment Back (episode credits) or If I Could Take This Moment Back (album) is a duet song sung by Rapunzel and Eugene during the Season 2 premiere episode, Beyond the Corona Walls.
Rapunzel: When I let him walk away
What if I had spoken "stay"?
Why did I go on concealing
The confusion I was feeling?
Now I'll never get to say
All the things I should have said
Now there's no more love, just echoes of
A life we should have led
If I could take that moment back
If he were here beside me still
I'd let him see inside my heart
Now he never will
Eugene: Maybe if I gave her time
Maybe if I didn't go
Maybe things somehow would change, but now
I guess we'll never know
Rapunzel: If I could take that moment back
Eugene: If I could turn back time, I would
Both: If we could make a brand new start
How I wish we could
Rapunzel: Wish I could take it back
But now it's gone for good
Eugene: Wish I had that moment back
