A group joke duke is out of control (9)
I believe the answer is:
abandoned
'is out of control' is the definition.
(thesaurus)
'a group joke duke' is the wordplay.
'group' becomes 'band' (band can mean a group of people).
'joke' becomes 'one' (I've seen this before).
'duke' becomes 'd' (abbreviation).
'a'+'band'+'one'+'d'='ABANDONED'
(Other definitions for abandoned that I've seen before include "lacking in self-control" , "Dumped" , "Dropped" , "Wild" , "Forsook, left behind" .)
