The two went head-to-head and tried to out-sing each other on Queen classics like “We Will Rock You” and “Somebody To Love” and “Another One Bites The Dust”. The two were joined by Queen band members, Brian May on guitar and Roger Taylor on drums, making for one show-stopping battle.

While Freddie Mercury can never truly be replaced, “American Idol” alum Adam Lambert has filled the shoes of the iconic singer and will join the band on tour this summer across North America.

Lambert has joined the band before, but Corden really wants the shot being such a big fan of the legendary band.

“In my head growing up I always thought I’d make a great frontman for Queen,” the host of “The Late Late Show” said. It’s clear both truly admire the iconic Queen frontman and do him justice with their riff-off.
