Six-time Grammy award-winning artist John Legend joined double Oscar winning Indian music maestro A.R. Rahman to present a picture of perfect harmony on stage as Mumbai-set "Slumdog Millionaire" swept the Oscars.

Both performers were joined in a multi-star cast of performers playing in a medley of three Oscar-nominee songs - "Jai Ho" and "O Saya" from "Slumdog Millionaire", and "Down to Earth" from "WALL-E" - at the annual Academy Awards ceremony at the Kodak Theatre here Sunday night.

The two artists got a chance to meet for the first time backstage and spent quite a bit of time discussing music and future projects.

"It's great to see AR get the global recognition he deserves for not only 'Slumdog', but his body of work. A lot of people don't know this, but AR's music has been consumed by more people than almost any artist out there," stated Legend.

"I look forward to future opportunities like tonight."

The Oscars presented a moment of serendipity for Legend, whose performance on stage for WALL-E ended with a joint duet with AR fusing all nominee performances together at the finale.
