Whakaotihia te rerenga e whai ake nei: I te tau 2006, i puta a Richardson ki "The Comedy Zone" i te Edinburgh Festival. I whakaotihia e ia he haerenga 60-ra o Ingarangi me Iraki me Alan Carr, a ka puta ia ki te "The Comedy Store" a Paramount. I te tau 2007, ko "Spatula Pad" (te whakaaturanga takitahi tuatahi a Richardson i te Edinburgh Festival Fringe) i whakawhiwhia ki a ia he tohu Best Newcomer i te
Ngā Tohu Waiata o Edinburgh. I wini a Richardson i te Tohu Chortle 2008 mo te Mahi Whakatika Pai rawa atu, ana ka whakaatuhia te "Dogmatic" (tona whakaaturanga takitahi tuarua) i te Edinburgh Festival Fringe. I muri mai ka kawea e ia tenei whakaaturanga puta noa i te whenua i tana haerenga takitahi tuatahi. I puta ia hei rangatira kapa i te raupapa 2008 a Simon Mayo "Act Your Age" i runga i te BBC Radio 4.
