Worn Carpet makes this nightclub entertainment (5,4)
I believe the answer is:
floor show
'worn carpet makes this nightclub entertainment' is the definition.
'floor show' can be an answer for 'nightclub entertainment' (I've seen this before). I am unsure of the rest of the definition.
'nightclub entertainment' is the wordplay.
'nightclub' becomes 'floor' (I can't justify this - if you can you should give a lot more credence to this answer).
'entertainment' becomes 'show' (show is a kind of entertainment).
'floor'+'show'='FLOOR SHOW'
Can you help me to learn more?
(Other definitions for floor show that I've seen before include "Nightclub entertainment" , "Cabaret" , "not raised performance?" , "Performance not staged" , "Night club performance" .)
