The actor, whose new film Taare Zameen Par is releasing on December 21, went to the Radio Mirchi studios at Lower Parel, Mumbai, and interacted with children.
Khan chatted with his fans over the phone for an hour and played their favourite songs. He also gave some acting tips.
Taare Zameen Par sees him play teacher to a dyslexic boy (played by Darsheel Safari), and is the actor's first attempt at direction.
