It must stop. Bombay has been Bombay for a very long time and was quite happy. Mumblesbai sounds silly. 'They' will tell you thats how the locals pronounce it. But the bleedin locals are translating the original Portuguese 'Bombahi' from Marathi into Hindi then into English. So its bound to sound a bit weird. Anyway, Londoners pronounce London 'Landing' but nobody is suggesting we change it. Bejing? Stick it. Kar-Bul? Never. The locals pronounce it like a dog coughing. Try that you BBC ponces. Eye-Rack? Septics taking the Mick. Bring back Constantinople or I for one am just going to start calling places by names I made up. Like what 'they' do. Burmongham anyone?
