Must-watch: Twenty One Pilots’ Tyler Joseph performs 'All I Do Is Win' with his Dad.

Twenty One Pilots performed at Firefly Festival over the weekend - which coincidentally was also a weekend that included Joshua Dun’s birthday, and Father’s Day - and to celebrate, Tyler Joseph brought out his Dad to perform a rendition of DJ Khaled’s iconic song, ‘All I Do Is Win’ [which was obviously co-written by Chris Joseph].

Let’s just say, this video is nothing short of amazing, and it also includes a crowd sing-along of 'Happy Birthday' for Josh.
