From Austin Improv Wiki
Moondogg was an improv duo.
 Press BlurbTheir press blurb, taken from a 2012 application to perform at The Hideout Theatre:
In 1947, blind street composer Louis Thomas Hardin adopted the name "Moondog" in honor of a dog "who used to howl at the moon more than any dog I knew of" (sic). In 2012, Arthur and Bob adopted the name "Moondogg" in honor of a Moondog "whose slithery rhythms will help inspire improvised scenes."
 "What's Your Deal?"Their answer to the "What's Your Deal?" question on a 2012 application to perform at The Hideout Theatre:
Arthur used to win best absurd characters, Bob best realistic characters. Joke's on yall though, when you think about it it's the exact opposite. This is honestly just a chance for us to play footsies and nerd out on an iconic street musician.
