Vaudevillian Olsen
I believe the answer is:
ole
'vaudevillian olsen' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ole that I've seen before include "(In Spain) bravo!" , "Spanish cheer" , "Madrid exclamation" , "Spanish victory cry" , "Well done! (Span.)" .)
