The makers of "Fan", starring Shah Rukh Khan, released the first song of the film on Tuesday, Feb. 16. The title of the song is "Jabra Fan", and it is the only song in this film, and thus, is trending as the "Fan Anthem," in which Gaurav Chandana (played by SRK) is seen dancing his heart out.

The makers have released the only song of the film before the trailer as promotion for the film and also to introduce Gaurav and his madness for superstar Aryan Khanna. 

In the second teaser of the film, Shah Rukh shocked everybody with his transformed look as Gaurav. This character is a huge fan of Aryan Khanna, which is also played by SRK, but the story revolves around Aryan's "fan".

Composed by Vishal-Shekhar and sung by Nakash Aziz, the "Fan Anthem" is essentially a tribute to fans across the world. The actor launched the song at Hansraj College in Mumbai on Tuesday. Scheduled to be released on April 15, "Fan" is directed by Maneesh Sharma.

Earlier, SRK had revealed that this film has scenes from his old films as well. But, the interesting part is the makers have not taken clips from the past films of SRK, but have reshot those scenes and recreated those sequences.

"There are dialogues from my previous films which we have been revisited in this film. We have reshot all the clips again as Aryan Khanna," Shah Rukh had told DNA.

"There's one from 'Baazigar', the one where I say, '15 saal se jo khoon mere ma ke ankhon mein aansu banke behta raha...'. But we haven't taken 'Baazigar' clips, but simply reshot them. So the dialogues are still the same. I have only said it once again in this film," SRK said.

Meanwhile, Shah Rukh is also shooting for his second film this year, "Raees", in Gujarat, which is expected to be released during Eid.
