Where or When Lyrics

It seems we stood and talk like this before
We look at each other in the same way then
But I can't remember where or when
The clothes you are wearing are the clothes you wore
The smile you are smiling you were smiling then
But I can't remember where or when
Some things that happened for the first time
Seem to be happening again
And so it seems that we have met before
And laughed before

And loved before
But who knows where or when
