Gang boasted (4)
I believe the answer is:
crew
This clue is a double definition.
'gang' is the first definition.
(I know that gang can be written as crew)
'boasted' is the second definition.
('crew' is past tense of 'crow', meaning to boast)
(Other definitions for crew that I've seen before include "Vaunted" , "Ship's company - boasted" , "Work gang" , "Boat's workers" , "Gave wake-up call" .)
