[Verse 1]
I knew when I shook your hand
Saw it all from start to end
Didn't listen when you said your name; I said nothing
Didn't have the time to act
Couldn't make a moment last
If only I could just go back and do something

[Chorus]
Only a spark, gone in a moment
Only a notion, caught off your guard
Think with your heart, you know in a moment
Sometimes a notion is only the start

[Post-Chorus]
What could have been? What could have been?
What could have been will haunt you
What could have been?
What could have been will haunt you
Only a spark

[Verse 2]
Door closed as the minutes passed
White dot on the TV set
As the picture fades to black, I do nothing
There's a cheap taste to regret
Then you have to live with it
Could it all be different if I said something?
[Chorus]
Only a spark, gone in a moment
Only a notion, caught off your guard
Think with your heart, you know in a moment
Sometimes a notion is only the start

[Post-Chorus]
What could have been? What could have been?
What could have been will haunt you
What could have been?
What could have been will haunt you
Only a spark

[Chorus]
Only a spark, gone in a moment
Only a notion, caught off your guard
Think with your heart, you know in a moment
Sometimes a notion is only the start

[Post-Chorus]
What could have been? What could have been?
What could have been will haunt you
What could have been? What could have been?
What could have been will haunt you
