Where or When歌词

It seems we stood and talked
Like this before
We looked at each other
In the same way then
But I can't remember where or when
The clothes you're wearing
Are the clothes (that) you wore
The smile you are smiling
You were smiling then
But I can't remember where or when
Somethings 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
