Continue as before, getting the sons worried (5,2)
I believe the answer is:
press on
'continue' is the definition.
(I've seen this before)
'before getting the sons worried' is the wordplay.
'before' becomes 'pre'.
'getting' says to put letters next to each other.
'worried' indicates an anagram.
'sons' is an anagram of 'sson'.
'pre'+'sson'='PRESS ON'
'as' is the link.
(Other definitions for press on that I've seen before include "Continue (regardless)" , "Continue (with action)" , "don't stop!" , "Keep going forward" , "Continue going forward" .)
