Its really pathetic. You guys are really into negativity of accepting the facts. I know if you guys keep living for another 200 years you would definitely say that there was no country called Nepal.  Any way you can not deny that that song was not written by him. If so claim and prove it that the song was not written by him i am sure nobody will salute him for his song. I wish he had a song sung by himself. and may be you would say that the song was not in his own  voice also...... He can not come back to prove you and prove us that he wrote that song but would always in our mind.
