I'm pretty sure that's Sam Coomes playing his distorted "roxicord" (mystery keyboard/fuzz setup he keeps hidden in a wood box). Sam isn't in the band, but has played keys on some of their stuff. Awesome song.
I always heard a Muff. Have I been wrong? I saw them live, couldn't get a great look at the board.
Great band, btw. Got to meet Doug as well, super nice guy.
