Nobleman given award for organ piece?
I believe the answer is:
ear lobe
'organ piece?' is the definition.
(I've seen this before)
'nobleman given award' is the wordplay.
'nobleman' becomes 'earl' (earl is a kind of nobleman).
'given' is a charade indicator (letters next to each other).
'award' becomes 'obe' (I've seen this in other clues).
'earl'+'obe'='EAR-LOBE'
'for' acts as a link.
(Other definitions for ear lobe that I've seen before include "one embracing the stud?" , "Fleshy part of the head" , "that hangs somewhere below the vestibule" , "Flap on the side of the head" , "Commonly pierced part of the body" .)
