"Ye dil aur unki nigahon ke saaye" is a song from 1973 Hindi film 'Prem Parbat'. It is believed that the print of the film got destroyed over time and hence the film and its songs are unable to be viewed.
The song is here played back on the scenes of Madhumati (1958), primarily consisting scenes from the song 'Aaja re pardesi'. Both the songs share many similarities between them which makes this superimposition attempt quite real.
The soothing music by Jaidev and the haunting voice of Lata Mangeshkar are just breathtaking.

Music: Jaidev
Singer: Lata Mangeshkar
Lyrics: Jaan Nisar Akhtar
