Katharyn has performed all over the world and is a festival veteran with multiple international fringe festivals under her belt. She has received excellent critical review (without using an agent or PR 😜) for both her performances and her hour "Ew Girl, you Nasty." Kate Copstick of The Scotsman exclaimed, “This show is a blast!" while The Skinny and Fringefeed in Australia gave her ★★★★ and ★★★★1/2. Pop Dust noted most accurately that "You won't see many comics like Henson at the Fringe or anywhere else." Prior to moving to the UK, Katharyn hosted a show in the New York Comedy Festival three years running and formerly produced two weekly shows in New York City which she headlined. In 2023 she was selected as the sole comedian in PUMA’s Who’s Who of Contemporary Culture – London’s second edition.

Katharyn will be performing again at PERTH FRINGE WORLD. Adelaide Fringe in a split bill show with her husband called "Married At First Fight" and again at the Edinburgh Fringe Festival in 2024.
