Rock star lives? Wrong! (5)
I believe the answer is:
elvis
'rock star' is the definition.
(I know that Elvis is a rock star)
'lives? wrong' is the wordplay.
'wrong' indicates an anagram.
'lives' anagrammed gives 'ELVIS'.
(Other definitions for elvis that I've seen before include "'The King,' 50s pop idol" , "Musically, The King" , "'The King' (singer)" , "Lives for rock'n'roll king" , "Singer, 1935-77" .)
