Well it could be a test...
When we were going threw musicians in our search for a permenant one, we had one for a short while that would show up late for 8:00 service, and then show up late again,or not show for 11:00, yea that didn't last long, but we sang more foot stompers, old accapello hymns, and did fine with a guitar, and a drummer.
I don't know if is your style, but listen to Alvin Darwyn(i think) song "All Night". Or an old one," lillies in the valley", or "hide behind the mountain".
Getting the church involved helps also, hand clapping, standing and joining in with the chior.
