But after Saturday's insane Rock n' Soul Dance Party, it's fair to say the thunder has been stolen from the former Beatle. The core band of the night—led by My Morning Jacket's Jim James and Hall & Oates' John Oates—was a jam-tastic delight in itself, but the special guests were operating on another level entirely.
R. Kelly swung through to croon Sam Cooke's "A Change Is Gonna Come"—which was hypnotically divine—and the blues classic "Bring It On Home," which he naturally left dirtier than he found it. After the R&B star's absurdly cool two-fer, Billy Idol—looking exactly like the punk sneering at you from the cover of Rebel Yell—dropped in and ripped through T. Rex's "Bang a Gong (Get It On)."
Although both singers were Bonnaroo headliners, these appearances were still shocking—keep in mind Kelly and Idol had wrapped full sets of their own just minutes before taking the intimate Superjam stage.
The visual dissonance was incredible to soak in, too. It's hard to say whether seeing Kellz backed by Jim James and his lion's mane hairdo or Billy Idol rocking out next to John Oates and his soul patch was weirder to watch. Let's just say both were beautifully bizarre sights to behold.
