Aside from MCing Outside The Box, Brown tours the UK comedy circuit developing his own material. March 2007 saw him tackle the comedy clubs in New York City. After landing three open spots, he took on Village Lantern in Greenwich Village and on to the Broadway Comedy Club with its three rooms. On the first night he was in the smallest one and was only supposed to do five minutes, but the MC told him to stay on. He did over 15 minutes and on the strength of that, got invited back the next day to play the next room up. The middle room at the Broadway Comedy Club holds around 80 people. Brown did 25 minutes and got a standing ovation.

August 2007 saw a successful Edinburgh festival stint for Brown when playing the white half in a show called The Honky and the Wog. Sharing the bill as the black counterpart, was Paramount Comedy Channel's Nathan Caton. The both performed half an hour and received positive reviews as a result.

2008's Festival was spent in the Pleasance Cellar as part of the award-winning stand up show AAA.
