"'Once in a Lifetime Love" is a song written by Jason M. Greene who co-wrote the single with and was recorded by American country music singer Clay Walker. It was released on May 9, 2000 as the fourth and final single to his album Live, Laugh, Love. It peaked at number 50 on the Billboard Hot Country Singles & Tracks becoming his lowest charting single of his career as well as his first to miss the top forty.
In an interview with The Virginian-Pilot, Walker stated that Once in a Lifetime Love was one of his favorite songs and said, "It's probably the best vocal performance I've ever given. I was listening to Whitney Houston's version of I Will Always Love You - man, I want to write something like that."
During an interview with Billboard, Walker mentioned that producer Doug Johnson was crucial for the performance. Walker stated, "I think he got everything there is to get out of me."
The song is about a man who asks his lover if their love is a once in a lifetime experience and what would happen if they never had a chance at it. He ponders what would happen if he never told his lover he loves her.
Girl, I know you don?t really know me
Still I want you to listen closely, this might sound crazy
But after all, isn?t love like that, I would be crazy
To let this moment pass
What if I don't say what's on my mind and you walk away
I might live out my life and never feel this way
What if you are the one that I'm meant to love, what if tonight is the night
What if once in a lifetime love don?t come twice
And girl, take a chance, time is unfolding
We could be blessed without even knowing, just for a minute
Close your eyes and don?t take another breath
?Cause what if you miss it and it never comes again
And what if you don?t say what?s on your minds and I walk away
You might live out your lives and never feel this way
What if I'm the one that you're meant to love and what if tonight is the night
What if once in a lifetime love don?t come twice
I don?t wanna wake up by myself
Years from now wishin? that I?d told you what I felt
Your eyes are a window to your soul
If you don?t open up, I may never know
What if we don?t say what?s on our minds and we walk away
We might live out our lives and never feel this way
What if I am the one and you are the one, what if tonight is the night
What if once in a lifetime love don?t come twice
Oh girl, what if you are the one and I am the one
What if tonight is the night
