New Year song (4,4,4)
I believe the answer is:
auld lang syne
'new year song' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for auld lang syne that I've seen before include "New Year's Eve favourite" , "Old times, especially remembered with affection" , "New Year song" , "Hogmanay song" , "New Year's Eve ditty" .)
