Pianist Nero (5)
I believe the answer is:
peter
'pianist nero' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for peter that I've seen before include "Disciple" , "Some rob ..... to pay Paul" , "Rock-like apostle" , "-- Sellers, comic actor" , "- Sellers, twentieth century English comedian" .)
