Get away with dropping jazzy singing (4)
I believe the answer is:
scat
I believe this clue is a triple definition!
'get away' is the first definition.
(scat can mean to run away)
'with' acts as a link.
'dropping' is the second definition.
(I've seen this before)
'jazzy singing' is the third definition.
(I've seen this in another clue)
(Other definitions for scat that I've seen before include "Type of jazz singing - be off!" , "Go away quickly" , "Shoo!" , "Dropping" , "Animal droppings - small silvery fish" .)
