Three Dog Night, Joy to the World
I attended a Christmas service here locally in a Presbyterian church (I have no religious affiliation whatsoever). It was one hell of a rock concert, terrific sound system. Did not bother with the lyrics on the screens though
. Quite a slick production, they even had brought in a professional vocalist from Nashville.
IMO this seems to be a well conceived marketing plan to attract the youth. There was little to no preaching.
