I'm a little stuck... Click here to teach me more about this clue!

'spears raised regularly during' is the definition.
I can't judge whether this definition defines the answer.

'spear song' is the wordplay.
'spear' becomes 'gore' (I've seen this in another clue).
'song' becomes 's' (this could be a standard abbreviation of which I'm unaware).
'gore'+'s'='GORES'

Can you help me to learn more?

(Other definitions for gores that I've seen before include "Impales in beastly fashion" , "Pierces with horn like bull" .)

I've seen this clue in The Independent.
