Musician with good news for impatient undergraduate? (7)
I believe the answer is:
bassoon
'musician' is the definition.
(eg musician in an orchestra)
I can't explain the rest of the clue.
(Other definitions for bassoon that I've seen before include "It is played" , "Double-reed instrument" , "Instrument heard by Wedding-Guest" , "Large woodwind instrument" , "Tenor of the oboe family" .)
