Ever since the trailer of Sivakarthikeyan's 'Hero' landed there is huge expectations for the film and producer KJR Studios promised one surprise a day till the release of the film on December 20th. Yuvan Shankar Raja has sprung a delightful surprise for fans that Isaigniani Ilayaraja has sung a song in the film in his music.

This is the first time that Siva is associated in a movie with the legendary composer and he is one of the lucky younger generation heroes to lip sync for a song sung by Raja. Pa. Vijay has written the lyrics for the peppy number.

'Hero' directed by P.S. Mithran has Sivakarthikeyan and Kalyani Priyadarshan as the lead pair while Arjun, Abhay Deol, Ivana and Robo Shankar are the others in the supporting cast.

Guess what??!! There's a surprise track in #Hero sung by appa.. So happy to have recorded this song with appa. @Psmithran @pavijaypoet @Siva_Kartikeyan @kalyanipriyan @kjr_studios pic.twitter.com/Xp9xxM8pwq
