Drunkards given urgent message? About time! (4)
I believe the answer is:
sots
'drunkards' is the definition.
('sot' can be a synonym of 'drunkard')
'urgent message? about time' is the wordplay.
'urgent message?' becomes 'sos' (an SOS message sent in an emergency).
'about' indicates putting letters inside.
'time' becomes 't' (abbreviation).
'sos' going around 't' is 'SOTS'.
'given' is the link.
(Other definitions for sots that I've seen before include "Drunks" , "Sponges" , "Boozers" , "Habitual drunkards" , "Chronic drinkers" .)
