I believe the answer is:

ding dong merrily on high

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

'christmas favourite almighty drunken' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'fight?' is the wordplay.
I cannot really understand how this works, but
'fight?' could be 'dingdong' (I've seen this before) and 'dingdong' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for ding dong merrily on high that I've seen before include "Happy clappers up" , "carol?" .)

I've seen this clue in The Guardian.
