The band remained in Birmingham for a second show at the Ballroom as part of their current headline UK tour in support of their recent album Sinners Never Sleep.
The video opens with all the You Me At Six members and their team asleep following a heavy night clubbing for drummer Dan Flint's birthday.
"Not a lot's happening today because we're all a bit hungover," Flint later explained. "We partied too hard for my birthday last night and now we're all feeling a little bit sorry for ourselves.
"We don't even know where Matt Barnes is, to be honest," he joked. "We think he's lost - dead on the streets or something. We're not sure."
He added: "Today is a sleep day, but it's a Sunday so it's allowed."
You Me At Six will continue their Sinners Never Sleep tour at Dublin's Olympia Theatre on April 7.
