Italian composer has a revolutionary massage in India (9)
I believe the answer is:
cherubini
'italian composer' is the definition.
'cherubini' can be an answer for 'composer' (I've seen this before). I'm not sure about the 'italian' bit.
'a revolutionary massage in india' is the wordplay.
'a revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'massage' becomes 'rub' (rub can mean to massage).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'che'+'rub'+'in'+'i'='CHERUBINI'
'has' is the link.
Can you help me to learn more?
(Other definitions for cherubini that I've seen before include "composer" , "author of church music" .)
