English translation included. It seems kind of rough sometimes, and often a lot of words are spoken for a short translation, so I think some is left out. 

The Encyclopedia Of Indian Cinema says this about the film:

A successful romance featuring a classical
shehnai musician. Kishen (R. Kumar) is a
musical prodigy in love with Gopi (Ameeta).
Their union is opposed by Gopi’s widowed
mother Jamuna (Mishra) and by Kishen’s
adopted music teacher Raghunath (Ulhas)
whose daughter Ramkali (Guha) secretly loves
the musician. Later, when Kishen is a famous
radio musician, his benefactor Shekhar
(Bhansali) marries Gopi. In several scenes, the
love-stricken Kishen vows never again to play
the instrument with which he had wooed Gopi
and he drowns his sorrows in alcohol. The
film’s main asset is the extensive use of the
shehnai instrument, performed in playback by
20th C. India’s best-known shehnai maestro,
Bismillah Khan. In order to try to match the
music’s classical authenticity, an attempt was
made to present the story as a medieval
Sanskrit love legend
