John Bell’s chant, “Behold, I Make All Things New” would be an interesting recessional. It would be hard to know when to stop, but as it best sung acapella you could keep singing as you leave. The extract at AOV has some the harmonies to listen to. This is a nice guitar and voice version.
Behold, behold, I make all things new,
Beginning with you and starting today.
Behold, behold, I make all things new,
My promise is true, for I am Christ the way.

Out of interest, here is a sample of John Bell’s “Singing the Unsung” DVD course that we did last year.
