Who are you and who am I
To say we know the reason why
Some are born, some men die,
Beneath one infinite sky?
There'll be war, there'll be peace,
But everything one day will cease,
All the iron turned to rust,
All the proud men turned to dust,
And so all things time will mend,
So this song will end.

"Childhood's End", on Obscured by Clouds (1972)
