Once In A While lyrics

Once in a while, I would call
Asking only to find you there

Once in a while, I would call
Asking only to know

And once you were mine long ago
When the evening was warm and free
Once you were mine
When the evening
Was full with that glow

And who could have known
We'd have flown far away
From the way we were
Knowing the way we were
Once in a while
Once in a while

And who could have known
We'd have flown far away
From the way we were
Knowing the way we were
Once in a while
Once in a while

And who could have known
We'd have flown like two birds
To another place
Only to find our space
Once in a while
Once in a while
