Aw, you need a piano player. One more person to pack!
Good one! I've seen some of musicians at the Pentecostal churches -- guitars, drums, organs, fiddles and such. All that's missing is a mechanical bull and it'd be just like going to church at Billy Bob's! And I do mean that with good-natured humor since my intent is not to mock those worshiping differently. We in the coC get plenty of ridicule for the way we do things.
