Oh, gosh, great thread- my chorus focuses on songs of healing- with the view that to sing is to heal. Let's see... specific healing songs would be
Courage my soul
Ionn Da (Seal-woman's sea joy)
Sing 'til the power of the Lord come down (somehow folks who object to being preached at don't usually mind African-American spirituals from the slave tradition since they represent so much hope out of struggle and oppression)

Then for consolation, let's sing
I bid you goodnight
Hallowell from the latest Sacred Harp - refrain repeats the lines The dead lift me up... I see them face to face... powerful!

Hmmmmmm- I'll keep thinking and check back here.
Peace, Allison
