I don't think that there any songs re; the four republicans executed at Kilmainham. I've often wondered about it and have never come across any references to them in verse.

In fact very few people know about these men. I work at the Gaol as a tour guide and on Nov 17th every year without fail, a relative of Peter Cassidy's leaves a bunch of roses at the plaque where they were shot. Very poignant really. I'll have to write something about them myself. the 100th anniversary will be in 2 years time....that's if we've escaped Covid 19 by then??
