The song "Thumbi Vaa" gained massive popularity on release. Ilaiyaraaja re-used the tune in Telugu, Tamil and Hindi films. Balu Mahendra loved the tune so much that insisted having the tune again in his Hindi filmAur Ek Prem Kahani. The song was also used two more times by Ilaiyaraaja himself and once by Shankar Ganesh.It has incorrectly been indicated here that Shankar Ganesh has used Thumbi Vaa... tune. In the film Auto Raja-1982, Ilaiyaraja has composed the song Sangathil Kanatha Azhagu.... based on Thumbi Vaa... tune, and Shankar Ganesh has composed music for the other songs in the film. Balu Mahendra totally directed 23 films, in 5 languages. Except the 1st two films, he collaborated with Ilaiyaraja consecutively, for 21 films. He intended to collaborate with Raja in the 6 films, that he had already conceived, before icy death snatched him away. While other directors never used Ilaiyaraja for their hindi remakes, Balu Mahendra was steadfast in persisting with Ilaiyaraja, in all the languages. Their equation was symbiotic & synergetic, with Ilaiyaraja, unfailingly churning out enviable chart busters, for Balu Mahendra. An exceptional highlight of Balu Mahendra & Ilaiyaraja’s, creative bonding being, the eternal superhit Thumbi Vaa ….. from Olangal-1982, was used by them 5 times, in 4 languages Mal-1, Tamizh-2, Tel-1 & Hin-1, apart from in Paa by R. Balki & a Vocal-Orchestra Symphony version, in Raja’s [Concert in Italy–2004, titled as Mood Kaapi.
