Go in Scotland with southern bands (5)
I believe the answer is:
gangs
'bands' is the definition.
(I've seen this before)
'go in scotland with southern' is the wordplay.
'go in scotland' becomes 'gang' (Scottish dialect word for 'go').
'with' is a charade indicator (letters next to each other).
'southern' becomes 's' (abbreviation).
'gang'+'s'='GANGS'
(Other definitions for gangs that I've seen before include "Mobs" , "Criminal groups" , "bands" .)
