"I love Donna Summer so much!" Adam Lambert declared at his gig last night at Golden Gate Park in San Francisco. "Do you love Donna Summer?" The question was probably a rhetorical one, as Lambert likely would have launched into his cover of Summer's disco classic "Hot Stuff," in belated tribute to the legendary late tribute. It's a fine cover—and holy hell, we haven't heard that much cowbell in one jam since the days of "House of Jealous Lovers"—and Lambert does a good job of tying Summer back to modern day (and his own music) by medley-ing the song with his own "Cuckoo."

Speaking of Lambert covers of disco standards, you guys remember his cover of Yvonne Elliman's 'If I Can't Have You" from his American Idol days? How badass was that?
