This is almost the newest song I have: Swim Any Sea.
I have played this a few times live and people have been great about learning the chorus so they can join in! There is every chance I'll be asking people to sing along in future so if you want to swot up beforehand, here are the lyrics:
Woah, you're part of my soul
As if somebody out there was waiting for me
I'd move any mountain to bring you back home
Oh my love, for to find you, I'd swim any sea.
