If you are a worship leader using these calls to worship, I'd love to know! Just for July, 2011, could you post a comment, or drop me an email and let me know where in the world you are, what church you worship with, and how many children and adults you usually have in your congregation?
E.g. I am using these at St Stephens Presbyterian church in Timaru New Zealand. We have anywhere from 8 to 18 children and 50 -70 adults on a Sunday morning.
