Showed live nude dancing (8)
I believe the answer is:
unveiled
'showed' is the definition.
(unveiling is a kind of showing)
'live nude dancing' is the wordplay.
'dancing' indicates an anagram.
'live'+'nude'='livenude'
'livenude' is an anagram of 'UNVEILED'.
(Other definitions for unveiled that I've seen before include "Shown for the first time" , "Took cover off - revealed" , "Removed concealing drapery from as in ceremony" , "Revealed, uncovered" .)
