This is a fun, if lyrically simplistic, reggae song written by a committee. The lyrics are by Tony and Lynn Melendez and Augie and Dawn Leal with music by Tony Melendez and Augie Leal.
The text is at spiritandsong. I can’t find a downloadable copy of the sheet music to purchase so you may have to get it in Spirit & Song Vol 1. You can hear the original here.
These people are commendably joyous while struggling with the syncopation, but throw in a key change to mix things up.
