Hearing it, Jimmy, Graham and Benny might have risen again! (3,5,2,5)
I believe the answer is:
the sound of music
'hearing' is the definition.
Both the definition and answer are adjectives.
Maybe they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
(Other definitions for the sound of music that I've seen before include "Musical (what else could it be?)" , "Film with Julie Andrews" , "Call of hounds" , "Show" , "that once enlivened the hills?" .)
