Red has drink during revolutionary song (5)
I believe the answer is:
rioja
'red' is the definition.
(I know that Rioja is a type of red)
'drink during revolutionary song' is the wordplay.
'drink' becomes 'oj' (orange juice).
'during' means one lot of letters goes inside another.
'revolutionary' says the letters should be written in reverse (letters revolve around).
'song' becomes 'air' (air can mean a piece of music).
'air' backwards is 'ria'.
'oj' put into 'ria' is 'RIOJA'.
'has' acts as a link.
(Other definitions for rioja that I've seen before include "wine region" , "Popular Spanish wine" , "it comes from grapevine" , "North Spanish wine" , "kind of red" .)
