Different thing - stick to disco (9)
I believe the answer is:
nightclub
'disco' is the definition.
(I've seen this before)
'different thing stick' is the wordplay.
'different' indicates anagramming the letters (letters placed in a different order).
'stick' becomes 'club' (club is a kind of stick).
'thing' anagrammed gives 'night'.
'night'+'club'='NIGHTCLUB'
'to' is the link.
(Other definitions for nightclub that I've seen before include "Social venue" , "Hot spot" , "Haunt" , "Entertainment centre" , "one of the high spots" .)
