The grand finale was a thunderbolt with master blaster Sachin Tendulkar gracing the stage of Indian Idol 9. Sachin was welcomed with loud cheering as always. It was a dream come true for Indian Idol contestant Thupten Tsering to meet Sachin in person after the cricketer had tweeted on seeing his performance in audition round. The legend made it a point to laud Tsering's grit and determination.

Also, Sonu Nigam who has collaborated with Sachin Tendulkar for the iconic cricketer's debut track – ‘Cricket Waali Beat’ launched then too.

The audience also got to see the performance of Sunil Grover on the show. The actor donned the avatar of Dr. Mashoor Gulati and Rinku Bhabhi on the show and sent the judges, Anu Malik, Farah Khan and Sonu Nigam, on a laughter ride. Post his performance, Sunil got extremely emotional as Farah Khan praised him saying it takes a lot of pain to be able to deliver such humor. Sunil also related to Khuda Baksh and told judges how hard it is to make it big in the cities for people who come from a village where you do not even have televisions.
