primary choir

I am co-leading one of the kid's choirs at church this year and I am having a blast. Hopefully the kids are too, but our song selection is getting a bit repetitive... I am not sure the kid's mind, but I don't know I can sing Deep and Wide many more times... Does anyone have any ideas? I am talking about 25 K-2 graders. They also love Lord I Lift Your Name on High... Something fun and contemperary would be good. Or a simple hymn? We have done O How I Love Jesus and Amazing Grace. Anything that has motions, clapping, yelling... Here are the rest of our favorites...

-Give Me Oil in my Lamp (and we already made up our own verse...)
-I am a C... I am a CH... I am a CHRISTIAN...
-Kwake Jesu (Swahili)
-King of Kings
-I've got the Joy (rockin' version)
-Go Tell it on the Mountail (getting ready for Christmas already)
-Little by Little (I remember liking this one as a kid, and have forgotten a whole chunk of the song, but they like it...)

So, any ideas, leave a comment...and if you get a chance, come see us sometime! We are quite a show.
