Crossword Genius

Pairs originally from Bolshoi lead Roman dance (6)

Ross

I believe the answer is:

bolero

'dance' is the definition.
(I know that bolero is a type of dance)

I cannot understand how the remainder of the clue works.

(Other definitions for bolero that I've seen before include "Arrange to rob Leo during the dance" , "Lively Spanish dance" , "Rob Leo of his short jacket" , "Spanish dance; Ravel's best-known work" , "Ravel work; jacket" .)

I've seen this clue in The Times.
