You might try this progression, too; the quick minors (half measure, most of them) lend the song an air of impending tragedy.

I start with a walkdown of G, D, and C, using the C for the pickup notes on each verse, then (over the words in parentheses)

First line: G (song), Em (evening), G (it), C (not), G (sad) Second line: Em (adding), D (sorrows), C (troubled), G (land)

This repeats through the verse.

Chorus: C-G (roses), C-G (roses), C-G (roses), Em (tears), D (people), C (together)

And back through the walkdown.
