At 9:53, start playing some instrumental music for ambience for 7ish minutes. You could just noodle or do a specific song/prelude. No singing. Service starts at 10 so you just play until you hear the zoom recording begin and the first speaker begins the service.
Opening song: Sanctuary 2 songs, as you mentioned, and I can send you ahead of time the topic and let you know my thoughts on what you're thinking.
Closing song: Currently One Light but from conversations with Dr David will likely be switched to Let There Be Peace on Earth in the next few weeks. I will provide the specific lyrics because we have a certain set of words that are approved for us to use. Do you know it already?
We would send you an Order of Service to follow along with. There is now a platform assistant to do all of the speaking throughout the service so all you would have to do is sing and play, or say something about your song if you'd like. The only thing you'd likely need to say is at the very end after the closing song, there is one sentence in the script for the musician to remind folks that they can stay online for fellowship. That's because at that point, the musician is the only one on mic. That said, if you'd prefer, we could just have the platform assistant say this before the closing song and that would be an easy change.
