Yeah, that could have hurt her and baby Jesus. Off the top of my head I can't think of a song that says Jesus was born in manger. However, it is still morning. There are several that are very nice tunes and certainly remind us of Christ's birth but aren't 100% technically/biblically correct.Joy to the World could be more than a Christmas song. I guess it is so linked to Christmas that people would not want to sing it any other time.But on every once in a great while I hear O Come All Ye Faithful at other times.
