Party offering drinks facility? Then get canned, drunk! (4,5)
I believe the answer is:
barn dance
'party' is the definition.
'drinks facility? then get canned drunk' is the wordplay.
'drinks facility?' becomes 'bar'.
'then get' says to put letters next to each other.
'drunk' indicates an anagram.
'canned' with letters rearranged gives 'ndance'.
'bar'+'ndance'='BARN DANCE'
'offering' acts as a link.
(Other definitions for barn dance that I've seen before include "Kind of social event with traditional music" , "Country social gathering" , "disco at the farm" , "Hoedown" , "Country entertainment" .)
