Perhaps Julie wanders about (7)
I believe the answer is:
andrews
'perhaps julie' is the definition.
(actor Julie Andrews is an example)
'wanders about' is the wordplay.
'about' is an anagram indicator.
'wanders' anagrammed gives 'ANDREWS'.
(Other definitions for andrews that I've seen before include "See 3" , "eg Julie or Eamonn" , "See 22" , "Julie --, actress and singer" , "Dame Julie - -" .)
