Stuff found in Grieg or Gershwin? (5)
I believe the answer is:
gorge
'stuff' is the definition.
('gorge' can be a synonym of 'stuff')
'in grieg or gershwin?' is the wordplay.
'in' indicates the answer is hidden within the clue.
'GORGE' can be found hidden inside 'grieg or gershwin'.
'found' is the link.
(Other definitions for gorge that I've seen before include "In which a river may flow" , "Ravine; feast" , "not fast" , "Chasm; overeat" , "Cheddar, say" .)
