A musical country, I hear (6)

I believe the answer is:
grease
'a musical' is the definition.
(Grease is a film musical)
'country i hear' is the wordplay.
'country' becomes 'Greece' (Greece is a European country).
'i hear' indicates a 'sounds like' (homophone) clue.
'greece' is a homophone of 'GREASE'.
(Other definitions for grease that I've seen before include "Fully aware, astonished" , "Film with Travolta and Newton-John" , "Musical that sounds like a country" , "Rock musical" , "Thick lubricant or frying oil" .)
