1984 Van Halen song, or a Central American country (6)
I believe the answer is:
panama
I believe this is a double definition.
'1984 van halen song' is the first definition.
(I've seen this in another clue)
'a central american country' is the second definition.
(country in Central America)
(Other definitions for panama that I've seen before include "city" , "Criticise" , "Great canal in middle America" , "Style of hat" , "Country and straw hat" .)
