Tenor gets musical man out of head on rare port (9)
I believe the answer is:
trondheim
'port' is the definition.
(I know that Trondheim is a port)
'tenor gets musical man out of head on rare' is the wordplay.
I cannot really understand how this works, but
'tenor' could be 't' and 't' is located in the answer.
'man' could be 'ron' (man's name) and 'ron' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trondheim that I've seen before include "Norwegian city" , "'Nidaros'" .)
