Impromptu Killers gig in Vegas?

Last night @kellanb posted the following on Twitter

"Just went out for beers and stumbled upon the killers minus Brandon Flowers playing an impromptu show. #kewl"

Could this be true?  Are our boys missing the limelight and ready to come back to us?  Here's hoping 'Boots' sparks off their early return in 2011.  We've missed you guys.
