Before taking a big lead and turning into an independent music composer, we all know AR Rahman was under the guidance of musical genius Illayaraja. However, that does not mean he is always correct but needs correction. And who better than Ilayaraja to correct AR Rahman.  

At an event, Rahman was invited to felicitate his Guru and as an honour was asked to recall his journey with Ilayaraja. The star composer remembered his association and said he was given notes for Moondram Pirai and asked by Ilayaraja to prepare notes.

The master then said on the stage that Rahman rendered a small composition in Punnagai Mannan. The host at the event Suhasini asked AR Rahman to play the same. Rahman tried to play the notes on his phone keyboard. But the fans wanted more. Then the music composer was given a keyboard to play the same.

As his fingers created magic, the sounds made the crowd scream in excitement while the title track of Punnagai Mannan rang in their ears.

Based on the request, the host then asked Ilayaraja to sing and Rahman to play the keyboard for another song.

While the music maestro sang a small bit from Mouna Ragam's Mandram Vantha Thendral, Rahman made the audience cheer.

Before ending the small 'jugalbandi' Ilayaraja corrected Rahman on the notes he missed on stage and laughed.

"Unaku teriyon illa" (You know it) said Iilayaraja pulling the Oscar winner's leg.
