Mumbai, Mar 15 (IANS): Megastar Amitabh Bachchan says he has recorded two songs for different projects at his friend and late Bollywood singer-composer Aadesh Shrivastavas studio here.

"Singing at the studio I often visited -- the studio of Aadesh Srivastava... He left us… For a better place… We left ourselves in his memory," Amitabh posted on his blog on Tuesday night.

"Two songs within minutes -- one for the song done by that talented Papon on the Brahmaputra river and the other for Navratna Oil the one I endorse... A fun version, adding bits and pieces to an already given track, but giving additions in the company of music director Rohan, is always fun, he added.

The "Piku" star shared that while recording songs, he always feels some "madness" in it.

"There is some madness that always prevails at such moments… A madness to just loosen up, be light, be in sun and in sunshine, be away from any bindings limits and barriers," he wrote.

On the acting front, Amitabh is currently gearing up for the release of Ram Gopal Varma's "Sarkar 3", which also features Jackie Shroff, Manoj Bajpayee, Amit Sadh and Yami Gautam.
