Well, I picked up another tidit - there's a song called "There Is More Love Somewhere" on a CD called River of Life/Harmony One by Bernice Johnson Reagon of Sweet Honey in the Rock. The Sound clip here assures me that it is indeed the right song. The only lyrics I found on the Web were the same as the one verse Dani posted. I think it's a "zipper" song that you can zip about anything in that you want.

I found the CD. Here are the lyrics in the CD booklet. Bernice Johnson Reagon says she learned the song from Bessie Jones.

There is more love somewhere
There is more love somewhere
I'm gonna keep on 'til I find it
There is more love somewhere

(There is more peace, happiness, joy)
