JAY-Z thrilled fans during his set at Britain's Isle of Wight festival on Friday night (11Jun10) with guest performances from Kanye West and Mr Hudson.
The hip-hop mogul was headlining the event with an 80-minute show, and during the slot he introduced Mr Hudson to the crowd on hit track Forever Young.
He was then joined by West, who rapped on Run This Town, to rapturous applause from fans.
The 99 Problems hitmaker also used his set to pay tribute to U.S. President Barack Obama, telling the crowd, "After 44 tries we've got a black president, we changed the world. And somebody in this field will change the world."
