Mark Thomas was born in South London. His mother was a midwife and his father a self-employed builder (and ex lay preacher).Thomas was educated at Macaulay Church of England Primary School, Victoria Rise, Clapham until 1974, where his party trick was to recite the first verses of the four gospels from memory, and then the independent Christ’s Hospital School. He went on to be awarded a degree in Theatre Arts at Bretton Hall College.
Prior to his most renowned vehicle, The Mark Thomas Comedy Product, Thomas was a frequent guest comic on the BBC Radio 1 show The Mary Whitehouse Experience, where he would do a routine about a specific topic of the week and involve studio audience members in the discussions. He would also occasionally play parts in sketches written by the show’s main performers. He then became the resident stand-up comic on Saturday Zoo, a Channel 4 comedy series first screened in 1993 and appeared on an episode of Have I Got News For You. He also co-presented the highly successful Radio 1 comedy talk show Loose Talk with Kevin Day, and is also a founder member of the London Comedy Store’s hard hitting Cutting Edge show
