Jagjit-Gulzar's 'Koi Baat Chale' released

The eight-song album, brought out by Sony BMG, comes seven years after the duo got together for "Marasim" in 1999.

After the launch, Gulzar said in front of a capacity crowd at the Siri Fort auditorium: "Jagjit Singh is undoubtedly the best singer across India and Pakistan."

"This crowd is for Jagjit Singh and not me," he joked.

This was followed by a concert in which Singh rendered several of his famous songs. His opening song "Zindagi kya hai" was from the new album.
