Look, there's George with his daughter! (6)
I believe the answer is:
gander
'look' is the definition.
(informal term for a look or glance)
'there's george with his daughter' is the wordplay.
'there's' is a charade indicator (letters next to each other).
'george' becomes 'g'.
'with' becomes 'and' (I've seen this before).
'his daughter' becomes 'er' (I can't explain this - if you can you should believe this answer much more).
'g'+'and' is 'gand'.
'gand'+'er'='GANDER'
(Other definitions for gander that I've seen before include "Looking at something - ranged (anag)" , "Male goose - quick look" , "Goose sauce is good for it" , "A butcher's -- bird" , "Male bird - look" .)
