Keen to hear this (5)
I believe the answer is:
dirge
'keen' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dirge that I've seen before include "Requiem" , "Mournful music" , "Dragging piece" , "part of funeral, perhaps" , "Threnody" .)
