Bobert I witnessed the power of song for myself. It was a sunday service in a local home one lady grunted and cursed the whole way through all the modern hymns they sang. some of them got upset but one of the older men in the group looked at her then quietly began singing "Jesus loves me this I know" He had barely got the first words out when she sat up straight and sang along as clear as a bell. He looked at the other members then told them we are having a change of hymns he then pulled an old redemption hymn book out of his bag (Redemption hymn singing was very strong on the island for many years) and began singing with his new friend joining in every one.
