One of the very few films to have a single cabaret song performed by 5 leading dancers of the time: Helen, Faryal, Sonia Sahni, Jayshree T and Bindu. Versatile singer Asha Bhosle has sung the song by frequently changing her voice texture for matching with all 5 dancers. All except Bindu, appeared just for part of this song. Bindu had a role also.
The song Yaar Ki Nigah was not an original song from the soundtrack of Dharma. But this was from the 1967 film, night in London, which was also produced by S.K.Kapur, who produced Dharma too.
