They are losing enthusiasm
I figured based on the verses we talked about, Peyton would want to try "The Greatest Command" aka "Love One Another." Even they knew better than to try four parts together. One for each boy, and one for each of two girls. I have one really quiet girl who I joked would have to lip sync to a part. She smiled really big, so I am pretty sure she thought I was funny.
Our medley is a bit of a hot mess though. It's what's in our hearts that counts though.
