Depends which song and when. I recall reviewing a record in the 80s, height of the last lot of 'Troubles' [I think it was by Frank Harte], and remarking that it was perhaps not the best of times to be singing songs rejoicing at "all the dead khaki soldiers in Erin-go-Bragh", which might just put a fair number of people [e.g. the wives of such soldiers] off what was, all-in-all, a beautifully performed collection of fine songs. I would stand by that to this day; and don't think I was going outside legitimate criticism, or suggesting any sort of censorship [except perhaps some intelligent self-censorship] in saying so.
