Strange man resounds with a Puccini aria (6,5)
I believe the answer is:
nessun dorma
'a puccini aria' is the definition.
(I've seen this before)
'strange man resounds' is the wordplay.
'strange' is an anagram indicator.
'man'+'resounds'='manresounds'
'manresounds' anagrammed gives 'NESSUN DORMA'.
'with' is the link.
(Other definitions for nessun dorma that I've seen before include "air" , "Well-known aria from Turandot" , "Famous Puccini aria (Turandot)" , "Aria from Puccini's opera Turandot" .)
