Orchestra member wants wine to drink at home (8)
I believe the answer is:
clarinet
'orchestra member' is the definition.
(clarinet is an orchestral instrument)
'wine to drink at home' is the wordplay.
'wine' becomes 'claret' (claret is a kind of wine).
'to drink' is an insertion indicator.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'claret' placed around 'in' is 'CLARINET'.
'wants' is the link.
(Other definitions for clarinet that I've seen before include "Music-maker" , "that works off wind" , "Music maker" , "Wind instrument made from Clare tin" , "It's for playing" .)
