Playing on organ in Burmese city (7)
I believe the answer is:
rangoon
'burmese city' is the definition.
'Rangoon' can be an answer for 'city' (Rangoon is an example). I'm not certain of the 'burmese' bit.
'playing on organ' is the wordplay.
'playing' indicates an anagram.
'on'+'organ'='onorgan'
'onorgan' anagrammed gives 'RANGOON'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for rangoon that I've seen before include "Asian capital" , "old Asian city" , "It's now Yangon in Myanmar" , "Port and largest city of Burma" , "Former Burmese capital" .)
