A song and dance, notice (6)
I believe the answer is:
ballad
'a song' is the definition.
(ballad is a kind of song)
'dance notice' is the wordplay.
'dance' becomes 'ball' (ball is a kind of dance).
'notice' becomes 'ad'.
'ball'+'ad'='BALLAD'
'and' is the link.
(Other definitions for ballad that I've seen before include "romance" , "Slow romantic song" , "A simple or old song" , "Slow sentimental song" , "Simple song or poem" .)
