Sadowitz made his comedy debut in 1983 at a Glasgow club and secured a regular stand-up slot at the Weavers Inn pub on London Road in Glasgow. The pub was run by future comedian Janey Godley, and he got the gig after her brother Jim begged her to put him on. Sadowitz began travelling down to London to perform at The Comedy Store every two weeks for two years, making the 400+ mile journey via Stagecoach express coach. He moved to the city permanently in 1986, living with his mother in Hampstead until 2005. There, he began his first job working in Selfridges.
