The band travelled to Birmingham's Ballroom for a headline show in support of their third studio album Sinners Never Sleep.
The clip opens with the group and their roadies singing happy birthday to drummer Dan Flint. Matt Barnes joked: "So today is Dan's birthday and we have a lot of friends coming up. Some welcome, some not so welcome."
He added: "It's going to be a lot of fun and we're all going to get rowdy and f**k some s**t up."
Crowds outside the venue can be seen also singing happy birthday to Flint, while some fans brought balloons, cards and presents.
You Me At Six will continue their Sinners Never Sleep tour at London's Brixton Academy tonight (April 3).
