Wine bottles in for orchestra member (8)
I believe the answer is:
clarinet
'orchestra member' is the definition.
(clarinet is an orchestral instrument)
'wine bottles in' is the wordplay.
'wine' becomes 'claret' (claret is a kind of wine).
'bottles' indicates putting letters inside (bottle can mean to contain).
'claret' placed around 'in' is 'CLARINET'.
'for' acts as a link.
(Other definitions for clarinet that I've seen before include "Instrument in claret, strangely" , "Music maker" , "Woodwind instrument played by Artie Shaw and Benny Goodman" , "Source of music" , "Woodwind instrument - Artie Shaw played one" .)
