The Lord is good to me,
And so I thank the Lord,
For giving me the things I need,
The sun, the rain and the appleseed
The Lord's been good to me.

I like that one, too (the first line has descending notes,
and in the second line they ascend)

Another one we used to sign at camp was:

Back of the bread is the flour and
Back of the four is the mill and
back of the mill is the sun and the rain
and the Good Lord's will
