Since when did these PNG Praise and Worship Songs birth out?

THE HISTORY OF PNG PRAISE AND WORSHIP SONGS! Hi Everyone! Want to share a little bit about the history Papua New Guinea (PNG ) Praise and Worship Songs. PNG Praise and Worship Songs are dated back to 1960's by the Panticostal Churches in PNG who discovered the revival breakthrough from the Holy Spirit through songs. Since then the style of singing through hymn books were little much needed where most people had already been introduced to the new style of praise and worship. Without catogarising and putting differences between both styles, I have realised that the same Holy Spirit and the revelations from God's word is undoubtedly working in both styles. However one thing that really impresses me is that the Tok Pisin Language unites the 800 plus language speakers and so by composing songs via that beautiful language encourages and opens the way for the worshipers to really express themselves fully.
