The entire song appears to be just F, C, G...you can play this along with the actual song.
Excerpt:
Capo 4
F C G
It started off great, but who was to know
F
That love that is lost can not be let go
C G
You say it's my fault--ok, then I'll go
It's better to know
F C
Now there's nobody to argue with, cause I'm not home...
......and so on
