The Umbilical Brothers aren’t actually brothers, but the comedy bond between Australians Shane Dundas and David Collins has lasted for three decades and taken them all over the world with their dynamic duo act that mixes mime, slapstick and stand-up. They’ve performed on late-night for Letterman and Leno, after James Brown at Woodstock ’99, for the Queen of England, and most recently on The Late Show with Stephen Colbert. The Umbilical Brothers have a monthlong run of Speedmouse (re-squeaked), an updated version of their 2004 show, playing in New York City at Theatre 80, where I caught up with the fellas to find out how they’ve stuck together this long.
