Mamula Moon? Negaraku?

a week or two ago, LK was surfing the net on my laptop and his friend passed him this song called mamula moon... and at first we thought "what's this? why does it sound like some dean martin song... from that era or before that..." then it sounded so familiar... it was exactly like NEGARAKU!!! or should i say that negaraku sounds exactly like it? since it sounds like it came from a time even before our independence was achieved... its being talked about alot these days... i guess the conclusion of it all will be out one day and the truth will be revealed?
