I havn't the title nor many words to this beautiful, old, folk song. The first verse;

One day a mother went to a prison to see an earring, but precious son She told the warrden how much she loved him It did not matter what he had done

Refrain; It was a halo...sent down from heaven the sweetest gift...a mothers smile

Please help with the rest. I know that some great harmony can be achieved if it's done right. Any info would be appreciated. Thanks
