Jesse Manibusan wrote this call and response song, which was used at World Youth Day 2002 for obvious reasons. Malo Malo means thank you in Tongan. The song was part of his Missa del Mundo.
The text is at spiritandsong where you can buy the sheet music for download. Cantus Mundi has aggregated some good Youtube versions.
I can’t think of broad liturgical use for this (my lack of imagination probably) but with so many languages, a parish with many ethnicities may find a use for it.
I can think of some parishes in New Zealand which could use this one.
