Singers having sheets of paper for broadcast? (5)
I believe the answer is:
choir
'singers' is the definition.
(group of singers)
'sheets of paper for broadcast?' is the wordplay.
'sheets of paper' becomes 'quire' (quantity of paper - 25 or 24 sheets).
'for broadcast?' indicates a 'sounds like' (homophone) clue (I've seen 'for broadcast' mean this).
'quire' sounds like 'CHOIR'.
'having' is the link.
(Other definitions for choir that I've seen before include "Large group of singers" , "Carol singers?" , "Singers in harmony" , "Organised group of singers" , "set of singers" .)
