Who wrote the mero by dubliners?

There seems to be a misunderstanding. There is no known literary work or song titled "Mero by Dubliners."

It's possible there's a typo or that you're referring to something else. Could you please clarify:

* Are you sure about the title?

* Are you referring to a specific author or band?

* Is there any other information about this work, like its genre or a description?

With more details, I can help you find the information you're looking for.
