Nude appearing in club at last, live (4)
I believe the answer is:
bare
'nude' is the definition.
(synonyms)
'club at last live' is the wordplay.
'at last' says to take the final letters.
'live' becomes 'are' (both can mean exist).
The final letter of 'club' is 'b'.
'b'+'are'='BARE'
'appearing in' acts as a link.
(Other definitions for bare that I've seen before include "Without protective covering" , "Denuded" , "Stark - naked" , "Not clothed" , "Carried" .)
