The date of the speech is unknown. May be around 25 years old. This audio is provided by Shri Achintya Narayana Jena of Rourkela who had collected speeches of Manoj Das from different sources. We have tried to retrieve the audios from the cassettes which have become very old. Hence the hiss sound is coming in the audio.
Hope, the readers of Manoj Das will listen the old audio of his speeches.
