The song Once In A Lifetime is performed by Alan Jackson .
Some people have it and some people don't
Some people never will
And sometimes it's hard to know when you've got it
Sometimes it's perfectly clear
Well, I know it's out there, I've seen it happen
I know the way it should feel
'Cause there's no mistakin' that good kind of achin'
Of a once in a lifetime love
Once in a lifetime love
A love like we've all dreamed of
It may go disguised right before your eyes
A once in a lifetime love
So if you think you've got it
If you feel it inside you, don't let it slip away
You may not ever find what you never
Thought you'd have anyway
And if you've always had it and just realized it
You know how lucky you are
To wake up beside what some never find
A once in a lifetime love
Once in a lifetime love
A love like we've all dreamed of
It may go disguised right before your eyes
A once in a lifetime love
It may go disguised right before you eyes
A once in a lifetime love
