Kailash Kher and Pearl Jam

Two years back i heared from someone & even saw in bangalore times that our local hero Kailash kher(who started from plateform) is going to sing with the Pearl Jam(yes the legend) singer 'Eddie Vedder'.... well & thats too on the occassion of the death annivarsary of another legend "Ustad Nusrat Fateh Ali Khan Sahib". That's on 16th August.. well i dono it ever happened or not... they ever sang together or ever came on the same stage.? Any light on this topic will be appreciated. I checked his site as well
