When I heard the title score of Hey Ram, I was literally blown away by the choral piece which was of international standards. This has become one of my favourite pieces along with Lajja title score, which is another amazing piece.
Unfortunately, this is a very short piece. Also, this theme being Mahatma's theme, appears only in one place in the movie, after Mahatma is shot in the climax. I wish Maestro composes full length choral pieces based on such themes.
This video also has a brief clipping of Pt. Ajoy Chakraborty recording with Maestro, for Har koi samjhe song.
