Adam Lambert Performs 'Detroit Rock City' and 'Rock and Roll All Nite' with Kiss

Lambert started things off solo, wearing a studded, sorta-angelic ensemble (leather epaulet, withwings and all), performing a somber, falsetto'ed version of "Beth." Then as the pyro hit, Kiss themselves descended from the heavens and launched into a big-time take on another staple (from the same year, 1976), "Detroit Rock City."

Lambert strutted and belted it out, drawing "Wow ... Did he just hit that note?" looks from guitarist Paul Stanley — and wearing a pair of platform boots that made him right at home with the glammed-up dudes in Kiss.

KISS performed their classic songs "Detroit Rock City" and "Rock And Roll All Nite" earlier tonight (Wednesday, May 20) on "American Idol", the annual reality show and singing competition. They were introduced by finalist Adam Lambert, who sang the KISS classic "Beth" prior to the band taking the stage (with Adam joining in). According to Newsday.com, "guitars [got] destroyed, fire [flew], and Adam close[d] with his trademark scream, looking right at home (gold platform boots and all). Audience [went] nuts."
