Classic music. Shared on request.

Track 1: Title Music and Incidental Music. Rahul Dev Burman played the harmonica in all the tracks. Milon Gupta played it for the background score and most probably for the title music too. Manohari Singh played the saxophone in the lovely title music.
Track 2: Raahi Manwa Dukh Ki Chinta - superb, soulful rendition by Mohd Rafi. Excellent lyrics by Majrooh Sultanpuri.

Great music by by Laxmikant Pyarelal.

Vinyl rip (Odeon 1970 pressing).
