This a cappella arrangement of a traditional West Indian carol should be given a really lively performance. Clapping is indicated in a couple of places but freedom should be taken to add other rhythmic clapping where thought appropriate.
There are also opportunities to incorporate some use of glissando: an example would be in the bass voice at the beginning, sliding from D down to G.
The entry of the bass, heralding in the Chorus, should be accented prominently.
Above all – ENJOY!
