The Deltones, Dumb John

The Deltones

The Deltones is an ensemble made up of members of some of iO’s premier ensembles, that performs a completely improvised musical.

The Deltones perform every Saturday night with a different opening team week to week.

Dumb John

Energy is at the heart of every ‘Dumb John’ performance. Their barb-wire wit and physical strength create oddly complex worlds filled with characters who are led by their unbridled emotions. Like a fist fight at an all-you-can-eat buffet, ‘Dumb John’ will kick down the door and leave you begging for another fistful of mashed potatoes.

‘Dumb John’ is Mike Geraghty, Katie McClain and Steve Plock. They play every Monday night as part of the show, “iO Improv All Stars”.
