Hi Brian!
As Vic said, a simple tune and simple arrangement, but very pleasant to listen to. Is that you singing? If so, well done in a style and tone that suits the message.
It sounds like your idea germinated really quickly!
Will your pastor/minister ask for ‘show and tell’ of congregation contributions? I.e. will you get to perform it?

PS Do you ever perform around Adelaide or are they all private events?
