Music-maker having wine outside home (8)
I believe the answer is:
clarinet
'music-maker' is the definition.
(I've seen this before)
'wine outside home' is the wordplay.
'wine' becomes 'claret' (claret is a kind of wine).
'outside' indicates putting letters inside.
'home' becomes 'in' ('he's home' can mean 'he's in').
'claret' placed around 'in' is 'CLARINET'.
'having' acts as a link.
(Other definitions for clarinet that I've seen before include "Musical wind instrument as played by Benny Goodman" , "It's for playing" , "Blow that!" , "member of orchestra" , "Single reed woodwind instrument" .)
