To my eternal shame (no, not really), I have sung Danny Boy, the original not the US version, on numerous occasions at folk clubs and sessions.

It is indeed very difficult to sing really well, and the only evidence I can offer is the fact that most times I have sung it have been the result of requests from people who have sung it before.

In point of fact, I consider it a very good song, not traditional but worth a listen.
