Some singers some paper reported (6)
I believe the answer is:
choirs
'some singers' is the definition.
'some paper reported' is the wordplay.
'some paper' becomes 'quires' (quantity of paper - 25 or 24 sheets).
'reported' indicates a 'sounds like' (homophone) clue.
'quires' is a homophone of 'CHOIRS'.
(Other definitions for choirs that I've seen before include "Singing groups" , "Groups of singers, in church say" , "Singing teams" , "Groups of singers, often in churches" , "Bands of singers" .)
