There is a sound sample of THIS OLD EARTH at Bob Zentz' web site, from which I transcribed these words:

Ask a child what really matters.
Ask a friend what he will do.
Ask the leaders you've elected,
But the answer lies with you.
This old earth has seen a lot o' livin'.
This old earth we've used from end to end.
Now it's time for mankind to start givin'.
This old earth could use a friend.

[The album it comes from, "Mirrors and Changes," is described as "a magnificant collection of Bob's early original songs."]
