The album has been composed by Babul Supriyo and features his duet with the 67-year-old actress.
While on a political trail with Supriyo, Malini had told him about her interest in singing.
The album features her duet "Aji suniye to zara, kya hai manjra" with Supriyo, apart from two Bengali songs which she had originally recorded for the legendary Kishor Kumar.
"I was excited to sing those two Bengali songs, which I had recorded for Kishor-da long back... I've been a dancer, an actress but today I can't believe as a singer I am in front of you, which I never thought of," Malini said.
Bachchan said that looking at Malini's ability to juggle many things, he was compelled to try a few things himself. "Jaya was saying Hema ji works so much, we don't work at all. She is in politics, goes to the Parliament, does dance, now she's singing too... We don't do anything. I want to assure you after today, even we will do something like this," Big B said.
Dharmendra recited a poem written by him and congratulated her on the launch.
Hema said she wanted to sing a song written by Dharmendra with Bachchan.
"They say you have to reinvent yourself. So Dharam Ji has reinvested himself....I have a wish. You write such good sher-o-shayari, so you write and I want to sing. Even Amit ji will sing...," she said.
To which Bachchan said, "It has been 42 years since my marriage and for 42 years I've been singing only..." Jaya joined the banter and said, "He has been singing for 42 years and I have been dancing!"
