Black couple welcoming composer over the road (9)
I believe the answer is:
boulevard
'road' is the definition.
(I know that boulevard is a type of road)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for boulevard that I've seen before include "Long, wide avenue" , "See 1" , "Broad tree-lined street" , "Wide city road" , "Broad urban road" .)
