Composer imbibes very English port (2,5)
I believe the answer is:
le havre
'port' is the definition.
(I've seen this before)
'composer imbibes very english' is the wordplay.
'composer' becomes 'lehar' (Austro-Hungarian composer Franz Lehar).
'imbibes' indicates putting letters inside.
'very' becomes 'v' (abbreviation).
'english' becomes 'e' (abbreviation).
'lehar' going around 'v' is 'lehavr'.
'lehavr'+'e'='LE HAVRE'
(Other definitions for le havre that I've seen before include "Port city of northern France" , "French Channel port" , "Northern French port" , "Port in Normandy" .)
