Cocktail which gained global fame thanks to a 1979 hit by Rupert Holmes (4,6)
I believe the answer is:
pina colada
(Other definitions for pina colada that I've seen before include "Perhaps contents of cocktail glass" , "alcoholic one" , "rum-based potation" , "Cocktail of rum, pineapple juice and coconut" , "Drink made of pineapple juice, coconut cream and rum" .)
