He lives anew! (5)
I believe the answer is:
elvis
'he' is the definition.
'lives anew' is the wordplay.
'anew' indicates anagramming the letters.
'lives' with letters rearranged gives 'ELVIS'.
(Other definitions for elvis that I've seen before include "Mr Presley" , "Legendary singer" , "Stop!" , "Singers Presley or Costello" , "Jailhouse Rock star" .)
