To repeat jazzy drama (8)
I believe the answer is:
operetta
'drama' is the definition.
(I've seen this before)
'to repeat jazzy' is the wordplay.
'jazzy' indicates an anagram.
'to'+'repeat'='torepeat'
'torepeat' is an anagram of 'OPERETTA'.
(Other definitions for operetta that I've seen before include "Short amusing opera" , "work of note" , "Make short work" , "light-hearted performance" , "La belle Helene, say" .)
