But the hills, the hills, they shall be there. Always? No, not even those.
What then shall be left of them? Only the fact of their having been. And when you are gone and I am no longer here, we too shall have been, and nothing can be quite the same again.
The title is not intended to imply that times to come will be particularly good; it's just the tense in the penultimate line. I later saw that "we too" could be read as "we two", though such was not my intention - at least, not consciously.
