Stand up and look at very good dancer (7)
I believe the answer is:
nureyev
'good dancer' is the definition.
(ballet dancer Rudolf Nureyev)
'stand up and look at very' is the wordplay.
'stand' becomes 'run' (as in to stand or run for election).
'up' says the letters should be written backwards (in down clue: letters go upwards).
'and' says to put letters next to each other.
'look at' becomes 'eye' (I've seen this before).
'very' becomes 'v' (abbreviation).
'run' backwards is 'nur'.
'nur'+'eye'+'v'='NUREYEV'
(Other definitions for nureyev that I've seen before include "Acclaimed Russian ballet dancer" , "Russian-born ballet dancer, who partnered Fonteyn, d. 1993" , "Rudolf -------, (1938-93), dancer" , "Rudolf -, Russ. dancer" , "Austrian ballet dancer, 1938-93" .)
