Lyrics:

Not a day goes by
Not a single day
But you're somewhere a part of my life
And it looks like you'll stay
As the days go by
I keep thinking, 'When does it end?
That it can get much better much longer
But it only gets sadder and stronger
And deeper and nearer
And simpler and freer
And richer and clearer

And no
Not a day goes by
Not a blessed day
That you somewhere come into my life
But you don't go away
And I have to say
If you do I'll die
I'll want day after day
After day after day
After day after day
After day
Till the days go by
Till the days go by
Till the days go by
