Now, nude dancing is not acknowledged (7)
I believe the answer is:
unowned
'is not acknowledged' is the definition.
(I've seen this before)
'now nude dancing' is the wordplay.
'dancing' indicates an anagram.
'now'+'nude'='nownude'
'nownude' with letters rearranged gives 'UNOWNED'.
(Other definitions for unowned that I've seen before include "not acknowledged" , "Not possessed" , "Not admitted to" , "Lacking a possessor" .)
