This text comes from A Shropshire Lad, a historical songbook transcribed on Wikisource and reproduced from the pinned revision linked below.
You smile upon your friend to-day,
To-day his ills are over;
You hearken to the lover's say,
And happy is the lover.
'T is late to hearken, late to smile,
But better late than never:
I shall have lived a little while
Before I die for ever.
