Song and dance witnessed at the gate (5)
I believe the answer is:
scene
'song and dance' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scene that I've seen before include "Pleasant view or public quarrel" , "Vista or stage setting" , "Where things happen" , "Drama; setting" , "A row - or a view" .)
