I have a great old recording with the verse:

"For we're just plain folks, your Mother and me
Just plain folks, like the old folks used to be
As our presence seems to grieve you, we will go away and leave you
For we're sadly out of place here, for we're just plain folks

The song is about an elderly couple who got to visit their son who ran away, became wealthy and was ashamed of his parents and background..
