'who know the score?' is the definition.
I can't judge whether this definition defines the answer.

'team captains' is the wordplay.
'team' becomes 'band' (both can mean a group of people).
'captains' becomes 'leaders' (I am not sure about this - if you are sure you should believe this answer much more).
'band'+'leaders'='BANDLEADERS'
