Party, wild do with German composer (12)

I believe the answer is:

balladmonger

'composer' is the definition.
(thesaurus)

'party wild do with german' is the wordplay.
'party' becomes 'ball' (ball is a kind of party).
'wild' indicates anagramming the letters.
'with' is a charade indicator (letters next to each other).
'do' after 'german' is 'germando'.
'germando' anagrammed gives 'admonger'.
'ball'+'admonger'='BALLADMONGER'

I've seen this clue in The Guardian.
