Singer ___ Folds (3)
I believe the answer is:
ben
'singer folds' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ben that I've seen before include "Big . . . is a famous London clock-tower" , "& 3 Across Epic film" , "Mountain; man's name" , "Boy for a Scottish mountain" , "High mountain in Scotland" .)
