Udit Narayan stormed out of the studio at a recording of a T-Series movie to be directed by Raj Kanwar, telling Malik that he'd never work with him henceforth.
It seems Udit wasn't getting the tune right during the rehearsal after repeated takes to which Anu politely asked him to buck up.
But Udit would have none of it and left. The song was later recorded in singer Abhijeet's voice.
