Edgar Wright (director) @edgarwright
Am heartbroken about Adam Yauch. Met him exactly a year ago in NYC. He was a fine, funny, talented gent. Will miss you Nathanial Hörnblowér.

Lobsang Nyandak (rep for the Dalai Lama)
Adam Yauch had been very keen supporter of Tibetan people and close friend of his holiness the Dalai Lama. Adam had helped us raise awareness on the plight of the Tibetan people by organizing various freedom Tibet concerts and he will be remembered by his holiness and the Tibetan people.

When Adam was sick he had met with his holiness on several occasions. The last time was in July of last year in Washington D.C. and his holiness blessed him and advised that lead a life of helping others and now he should be aware and face his challenges courageously.
