Theatre about to host prancing Tina Turner? (7)
I believe the answer is:
painter
'turner?' is the definition.
(JMW Turner is an example)
'theatre about to host prancing tina' is the wordplay.
'theatre' becomes 'rep' (repertory theatre).
'about' says the letters should be written in reverse.
'to host' is an insertion indicator.
'prancing' is an anagram indicator.
'rep' written backwards gives 'per'.
'tina' with letters rearranged gives 'aint'.
'per' going around 'aint' is 'PAINTER'.
(Other definitions for painter that I've seen before include "someone like Monet" , "a line connected to a boat" , "Bow tie" , "Bacon, perhaps" , "Sutherland?" .)
