We hear SRK has sung a rap song in his home production, Ra.One. The last time he held the mike was for Apun Bola in Mansoor Khan's Josh, over a decade ago.
The idea of making SRK sing came from director Anubhav Sinha and was seconded by music directors Vishal-Shekhar.
Sinha says, "When we told him that we want him to come and sing a song, his first reaction was, 'Are you mad, I am not coming'. Later he agreed to come and we hear it has turned out to be quite an interesting song.
