Tell Me Your Favorite Gather Songs

[Arshness]

Hi everyone!
I want to hear your favorite songs for singing at gatherings.
Calls/openings, Chants, Closings, Seasonal/holiday, even silly and kids songs.

I'm looking particularly for songs that are good for singing, easy enough for a group to pick up with the lyrics in front of them. I would prefer you link to lyrics and a youtube video with the melody at least if you don't mind.

Let's hear your favorites! Thanks!

I really like this song and we sing it in almost every circle, and I chose this video because all the rest were of the same recording, and I was looking for something more short and sweet, and this one has some words we don't sing but it is very sweet.
