Director Subhash Ghai revealed music composer AR Rahman records music from 9 pm to 6 am and spent 70 nights composing the music for the 1999 film 'Taal'. "When Kavita Krishnamurthy came...she was supposed to sing...antara and a mukhda," he recalled. Stating that they thought it'd be completed within one hour, the 79-year-old added, "Rahman told her to 'carry on'."
