Hear Bana ruined Cuban dance (8)
I believe the answer is:
habanera
'cuban dance' is the definition.
(I've seen this before)
'hear bana ruined' is the wordplay.
'ruined' indicates anagramming the letters.
'hear'+'bana'='hearbana'
'hearbana' anagrammed gives 'HABANERA'.
(Other definitions for habanera that I've seen before include "Steps" , "Cuban dance in slow duple time" , "Slow dance of Cuban origin" .)
