If we were to label the two services, it would probably be a consensus of the people at the earlier service (9:00 am) that it is the "traditional" service.
It is at this service that we sing more hymns, and for the most part that is the only real difference. The message is the same, and the basic elements are the same, but the only real difference is the order of worship and the music. Look below at a sample order of worship. Please note though, that this isn’t set in stone, but just a framework from which we use to celebrate God’s presence among us as we worship Him.
