One of the nicest Sacred Harp parting songs is this:

PARTING FRIENDS

Farewell, my friends, I'm bound for Canaan,
I'm trav'ling through the wilderness;
Your company has been delightful,
You, who doth leave my mind distressed.*
I go away, behind to leave you,
Perhaps never to meet again,
But if we never have the pleasure,
I hope we'll meet on Canaan's land.

(*alt: You do not leave my mind distressed)
