West Indian ballad (7)
I believe the answer is:
calypso
'west indian ballad' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for calypso that I've seen before include "character from Odyssey" , "Keeper of the Ithacan king" , "Caribbean dance" , "Satirical West Indian song and dance" , "W. Indies music" .)
