Where or when?

It seems we stood an' 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 you wore
the smile you were smiling
you were smiling then
but I can't remember where or when

Some things that happened for the first time
they seem to be happening again
and so it seems that we have met before
laughed before and loved before
but who knows where or when?
