Rogers partner (7)
I believe the answer is:
astaire
'rogers partner' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for astaire that I've seen before include "A satire about Fred, great Hollywood dancer" , "US dancer (Top Hat)" , "Fred --, dancer/actor" , "Fred -, twentieth century US dancer" , "Fred, immortal Hollywood dancer" .)
