Get non-Christians to play music at church?

Al asks the question.

What do you think? My leaning is towards 'No', partly just on gut. It feels wrong. I do feel music is part of the decisively Christian part of our gatherings in a way that washing up isn't. I also share the concerns of one of the people commenting on Al's post, that we want Christian mindset to govern the approach to the music.

Have you heard about how Ghostface Keller has even employed professional non-Christians to do music in his gatherings? What do you think of that?!!
