All Time Low Joined On Stage By 5SOS’ Michael Clifford

All Time Low were joined onstage in LA by 5 Seconds Of Summer guitarist Michael Clifford.

The pop-punks were playing LA’s Shrine as part of their Back To The Future Hearts U.S. tour, and invited Michael on stage for a storming rendition of fan-favourite, Dear Maria, Count Me In. Check out the videos below, and let us know what you think in the comments!
