Hurry back and watch Kirov's last dancer (7)
I believe the answer is:
nureyev
'dancer' is the definition.
(Rudolf Nureyev)
'hurry back and watch kirov's last' is the wordplay.
'hurry' becomes 'run' (running is a kind of hurrying).
'back' is a reversal indicator.
'and' says to put letters next to each other.
'watch' becomes 'eye' (I've seen this before).
'last' suggests the final letters.
The last letter of 'kirov' is 'v'.
'run' reversed gives 'nur'.
'nur'+'eye'+'v'='NUREYEV'
(Other definitions for nureyev that I've seen before include "Rudolf -------, (1938-93), dancer" , "Famous Russian ballet dancer" , "Russian-born ballet dancer, who partnered Fonteyn, d. 1993" , "Rudolf -, Russ. dancer" , "Austrian ballet dancer, 1938-93" .)
