Song produced by most uneducated (4)
I believe the answer is:
tune
'song' is the definition.
(I've seen this before)
'produced by most uneducated' is the wordplay.
'produced by' says the answer is hidden in the clue (the clue produces a copy of the answer).
'TUNE' is hidden in the letters of 'most uneducated'.
(Other definitions for tune that I've seen before include "temper" , "Song" , "Adjust for better performance" , "Adjust (car engine); air" , "Optimise the condition of" .)
