Roll in once drunk for work (8)
I believe the answer is:
nocturne
'work' is the definition.
(type of musical work)
'roll in once drunk' is the wordplay.
'roll' becomes 'turn' (turn can mean to roll over).
'in' means one lot of letters goes inside another.
'drunk' indicates anagramming the letters.
'once' with letters rearranged gives 'noce'.
'turn' going into 'noce' is 'NOCTURNE'.
'for' is the link.
(Other definitions for nocturne that I've seen before include "Pensive lyrical piece of music" , "Picture of a night scene" , "Dreamy piano peace popularised by Chopin" , "Pensive piano piece" , "Short romantic musical composition" .)
