Adam Lambert reunited with rock legends Queen in Kiev, Ukraine last night (June 30).The show, a benefit for the Elton John AIDS Foundation,  was one of six that Lambert performed with the classic British outfit this summer. John was also on the bill for the big night.

Lambert was beyond excited for the gig, telling ABC News (via Classic Hits and Oldies), “For me, personally, I think I’m gonna look back on this in years to come and kind of think, ‘Wow, what a treat. What an honor to be able to be asked to sing with legends.’ Their music is iconic and Freddie Mercury, for me, is obviously one the the very great performers in history and a definite idol for me.”

Despite being thrilled, it doesn’t mean the ‘American Idol‘ alum wasn’t totally nervous, either, especially since most Queen songs feature complicated and intricate vocal arrangements that require a wide range. Freddie Mercury has some big shoes and Lambert wasn’t necessarily trying to fill them! “There are a few [songs] that are daunting, let me tell ya!” Lambert said. “And then there’s some that I’ve sung many times before, so I’m excited for the challenge.”

Lambert, who previously performed with Queen at the MTV Europe Music Awards in 2o11, was stoked in general to “get up there and to pay homage” to Mercury and to “pay respect to his memory as a performer.” Based on the videos below, we think he  did a fantastic job!
