Play Boy. The same pair got an offer to sing for the Tamil film
Shri Krishna Leela in 1977 directed by
A. P. Nagarajan and one of the last assignments of composer

A. V. Ramanan composed film
Neerottam. However, it was "Poongathave Thaal Thirava" song for the film
Nizhalgal released in the same year and composed by
Ilayaraja that brought her to the front running singers list. It gave her a big career break and she went on to record more than 100 songs with Ilayaraja alone. She has also sung for other music directors namely

Deva and
