Some really easy songs to teach the youth choir would be:
Clap/Shout- Shekinah Glory
Highest Praise-Judith McCalister
I will bless the Lord-Joe Pace
Bless/Praise The Lord With Me-TD JAkes
Victory-tye Tribbett
Bless The Lord-Tye Tribbett
Grateful-Hezekiah Walker
Let's Celebrate-Timothy Wright
God Is Great-Kevin Davidson
Right Place-Rudolph McCissick-This is a REally Good One!
Pressure Into Praise-Lucinda Moore
That's the one's that i taught recently to the youth choir, we sing mostly upbeat songs, b/c the praise and worship team sings right before them on 4th Sundays when they sing... If u need to know some hymns then let me know.... Hope this helps, GOD BLESS!!!
