The Who will perform at London's 90,000-set Wembley Stadium on July 6th. The band -- who have only ever played at the original venue back on July 13th, 1985 for Live Aid -- will be joined by Pearl Jam's Eddie Vedder and Kaiser Chiefs, with other special guests still to be announced. The gig is truly a hometown gig for the Who, with the group's legendary late-drummer Keith Moon having been born in Wembley and raised in the nearby suburb of Alperton.

55 years after officially becoming "The Who," Pete Townshend told us he remains amazed at how massive a crowd he and Roger Daltrey can command simply by performing under the band's moniker: "It's so strange to have that brand that is bigger than either of us. That when we get together under that banner that attracts an audience that is not just old fans -- it's curious young people, people who are interested in our legacy and where we fit into the history of Western music -- and Western sociology."

Roger Daltrey, who's spent more time onstage over the past decade than he did in the 1980's or '90s combined, told us that playing live has little to do with a performer's age and everything to do with their soul: "I've always laughed at people who say, 'Oh, you're too old to rock n' roll.' I don't. . . To me, it's got nothing to do with your age or any of that. It's to do with the music and what that music itself generates."

Eddie Vedder -- who's taken the stage numerous times with Pete Townshend over the years -- has shared a mutual admiration society with Simon Townshend, Pete's youngest brother and the Who's touring guitarist. Vedder is also very close with the middle Townshend brother -- Paul Townshend.

On his 2012 album Looking Out Looking In, Simon Townshend recorded a salute to Vedder, titled "Electric Friend." Simon gave us the back-story to the Eddie Vedder tribute: "That was inspired by Eddie Vedder. I was in L.A. and I had a friend contact me from Washington saying they wanted to get Pearl Jam tickets. So I texted Eddie, and within a half-an-hour he got 10 people in to the show in Washington. But not only got them in; shown them around backstage, got them all drinks, y'know, chatted to them. And I just thought that was so wonderful, that I could just so quickly do. . . could get that contact, that I was inspired to write 'Electric Friend.'"
