Singer Presley (5)
I believe the answer is:
elvis
'singer presley' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elvis that I've seen before include "Mister Presley for one" , "'The King' (singer)" , "Singer, 1935-77" , "Stop!" , "Singers Presley or Costello" .)
