This here bit of showmanship is culled from The Killers' forthcoming (November 10th, to be exact) live DVD, The Killers: Live From Royal Albert Hall.
RAH is obviously a gorgeous, classy venue. Lead Killer Brandon Flowers does his best to de-flower-the-joint schtick in his pre-song banter, asking if the crowd if they're ready to "receive" their Sam's Town hit, "When You Were Young," as hard as they're going to give it to them. Naughty Mormon!
It's actually a dazzling performance from a band that's clearly feeling the energy, not only from the crowd, but from the hallowed halls of Royal Albert. Check out The Killers' live performance and the music video below.
