Arrange to rob Leo during the dance (6)
I believe the answer is:
bolero
'arrange to rob leo during the dance' is the definition.
(I've seen this before)
'arrange to rob leo' is the wordplay.
'arrange' is an anagram indicator.
'rob'+'leo'='robleo'
'robleo' with letters rearranged gives 'BOLERO'.
(Other definitions for bolero that I've seen before include "Arrange to rob Leo during the dance" , "Ravel orchestral piece" , "Kind of jacket or dramatic music by Ravel" , "attire" , "Spanish dance in triple time" .)
