UK Campbell moved to the
United Kingdom, having acquired a Global Talent visa in 2022. He performed at the 2022
Edinburgh Festival Fringe with his show simply titled
Comedy Show, which won the main prize. It was praised by the judges for its originality, surrealism and unexpected jokes.
The Times described him as "a nutball, but he controls his loopiness with deceptive precision" and said that the show was "exhausting, exhilarating and a touch of genius". Brian Logan in
The Guardian said "Campbell's imagination produces wonderfully adhesive images... there is now and then a core of robust observational comedy beneath Campbell's loopiness... None of it has anything to do with anything: it's the incongruity, taken to uncommon lengths, that's funny".
The Daily Telegraph review mentioned "one-liners and absurdist whorls of madcap". In 2023, Campbell was a contestant on
the sixteenth series of
Channel 4 comedy gameshow
Taskmaster, winning the series. On 29 March 2024, Campbell started co-hosting the ''Lucy & Sam's Perfect Brains
