Jay-Z And Justin Timberlake Perform ‘Holy Grail’ At Wireless Festival

By Maurice Bobb

Jay-Z and Justin Timberlake served up one heck of an appetizer to their upcoming “Legends of the Summer” tour, which kicks off in Toronto this week, with their first live performance of “Holy Grail” at London’s Yahoo! Wireless Festival Sunday (July 14).

The “Picasso, Baby” rapper joined JT on stage the previous night to assist the singer with “Suit & Tie,” but the biggest surprise of the show was Rihanna, who joined the Hov during his performance of “Run This Town.”
