Edinburgh Fringe Review: Caitriona Dowden – Sesh Head

August 19, 2026 at PBH Free Fringe @ Carbon, Room 1

Comedy is often best when it’s specific, and Caitriona Dowden has built a career on this principle. Her first hour was about Medieval theology; her second about apocalyptic dread, and the Medieval history thereof; and Sesh Head, her third hour, is about Irish and British folk music, and their roots in Medieval history.

Caitriona Dowden is, as she mentioned in this show to no one’s surprise, currently pursuing a PhD in Medieval history. This means that the specificity of her stand-up isn’t just a conceit to stand out in an industry saturated with comedians who cover the same common topics, though it does function as that. Dowden’s comedy comes from a genuine interest in her subject matter, and is backed by research into the field. Research that’s currently being undertaken to a PhD standard.

This is my third time seeing Dowden live, after I took a chance on a relatively unknown name in 2024, because she had an interesting show blurb and had won a new comedian award (Chortle Student Comedy). Punts like that don’t always pay off, but it did in this case, which is why I’ve returned for subsequent years, and have enjoyed watching her attain further success.

Dowden’s delivery has markedly increased confidence in this third hour, but still with her understated style that can betray the level of craft on display. She opens with some jokes about landlords, which are funny but seem out of place and oddly “mainstream” for her, until she folds them neatly into the less mainstream narrative.

This show features a fair bit of harp music, which Dowden plays live on stage. This is funny, as she manages to find ways to make jokes with harp notes, but it’s also lovely, and I frequently found myself closing my eyes and just enjoying a bit of pretty music to break up a busy day at the Fringe. I’ve seen many comedians with instruments on stage before, but why don’t more of them have harps? Why don’t they all soothe us with twinkly sounds throughout the hour so we can be more ready to take in the jokes?

The show is funny – I don’t want to let that fact get lost in all the words I’ve written about music and niche subject matter, because Dowden doesn’t let it get lost. She sometimes delivers her jokes in a tone so casual that it takes the audience a moment to realize they were jokes, but when we process the meaning work it out, that makes it all the more entertaining. There is funny commentary on modern folk music and historic folk music, British folk music and Irish folk music, Medieval living conditions and present-day landlord companies, and how all those things intersect. She brings her niche subject matter to life, and it’s a lot of fun for all involved.
