Hard Rock Turns 40 with a Massive Celebration in London’s Hyde Park

The Hard Rock brand, which encompasses restaurants, hotels and casinos, turned 40 years young over the weekend. In honor of the momentous anniversary, tens of thousands of fans turned out for the three-day Hard Rock Calling festival, held in London’s famed Hyde Park. In addition to headliners Rod Stewart, Bon Jovi and The Killers (the latter of which was witnessed by none other than Prince Harry), VH1 faves Train and You Oughta Know artist Lissie also appeared on the bill. Our VH1 news team was on hand and got some backstage time with some of the artists on the bill; take a gander above to get Train, Lissie and Pete Wentz’s thoughts on the occasion.
