It was Su(ma)ng by Mukesh

Saathi released in 1968.

Mukesh Chand Mathur sang the majority of the songs on the soundtrack of the film.

Interestingly, he was the only male singer to lend his voice to them.

However, my collection contained just one of those.

It was titled Mera Pyaar Bhi Tu Hai.

The lady who joined him behind the microphone for the song was Suman Kalyanpur.

It happened to be her only contribution to the soundtrack of the film.

Majrooh Sultanpuri penned the song, which was composed by Naushad Ali.

The song was four minutes and 22 seconds long.
