Big B has sung a song, Piddly, in Shamitabh, which has been composed by Ilaiyaraaja. Talking about how the song happened, Amitabh says, "It's a blessing to sing for a musician as illustrious as Ilaiyaraaja. It's a big blessing. But I must say, I couldn't work up enough bravery to sing in front of him. So, I requested him to send the song to me in Mumbai, practiced it in y own bathroom, and recorded it in a studio here. That's how Piddly happened."
