One lives and learns.
Pardon my ignorance. Never knew that C. H. Atma had sung Shankar-Jaikishen's compositions. That his classic "Rovoon Mein Sagar Ke Kinarey" (arguably second only to "Preetam Aan Milo" as his most recognized song) was an S-J composition!
That famous song featured in "NIRALA"* (Nutan's first acting role --- more of that later in the Lata Mangeshkar forum). But for me, this song was the 'discovery'! Glorious number.

*S-J utilized the talents of Rafi-sahab and Shamshad Begum and Lata-ji for the light-hearted songs, and C. H. Atma and Lata-ji for the "heavy-weight" numbers in this movie.
