Good man had an urge and joined up (8)
I believe the answer is:
stitched
'joined up' is the definition.
(I've seen this before)
'good man had an urge' is the wordplay.
'good man' becomes 'st' (abbreviation for saint).
'had an urge' becomes 'itched' (I've seen this in another clue).
'st'+'itched'='STITCHED'
'and' is the link.
(Other definitions for stitched that I've seen before include "Used a needle" , "after action in theatre?" , "Fastened with a needle and thread" , "Joined up" , "Bound" .)
