I don't know why
The world turns out to be
The way it is
As time goes by

Oh, I don't know why
True love turns out to be
The stuff between
Hello and goodbye

Looking back with 20/20 hindsight
We only tried to play our part
When selfishness is state of the art
You've just got to change the locks on your heart

No, I don't know why
True love turns out to be
The stuff between
Hello and goodbye

Looking back with 20/20 hindsight
We only did the best we could
As green as any Norwegian Wood
The acid test of fame we withstood

Now I don't know why
The world turns out to be
The way it is
As time goes by

Oh, I don't know why
True love turns out to be
The stuff between
Hello and goodbye
