“Come, Come, Whoever You Are” is a beautiful setting of a Rumi poem by Unitarian Universalist pastor and poet Lynn Ungar.
It can be sung in a round of up to four parts.
Here’s a recording.
And here are the lyrics:
Come, come, whoever you are,
wanderer, worshipper, lover of leaving.
Ours is no caravan of despair.
Come, yet again, come!
