Buddhist monk with musical instrument going about US city (9)
I believe the answer is:
kalamazoo
'us city' is the definition.
(I've seen this before)
'buddhist monk with musical instrument going about' is the wordplay.
'buddhist monk' becomes 'lama' (as in the Dalai Lama).
'with musical instrument' becomes 'kazoo' (I can't explain this - if you can you should believe this answer much more).
'going about' means one lot of letters goes inside another.
'lama' going into 'kazoo' is 'KALAMAZOO'.
Can you help me to learn more?
(Other definitions for kalamazoo that I've seen before include "I've got a gal in - (Glenn Miller)" , "US city" , "Michigan city" .)
