"Being the lead female singer on the tour was an unforgettable experience. I'm so grateful that Rahman sir trusted me with the task of delivering so many of his hits live on stage. I learned a lot about myself as a singer and performer during those 18 shows, and I'm so happy that parts of it have been captured and presented so beautifully in 'One Heart' for everyone to enjoy," Jonita said in a statement.

Her performances included songs of various genres, languages and even rap.
