Rogue put on uniform in farewell entertainment (10)

Ross

I believe the answer is:

vaudeville

'entertainment' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for vaudeville that I've seen before include "variety show" , "Variety entertainment" , "Musical and comedy entertainment" , "theatrical entertainment" , "American music hall" .)

I've seen this clue in The Times.
