Nine years ago I commented in this thread about "One Sunday Morning".

I use the song only to make a point... I doubt I have sung it for anyone in 20 years.

I have very few Irish roots, and a few more Scottish ones... none recent. My family were English and Welsh. I used to know an Armstrong who made a big thing about ethnic/cultural divisiveness, so I learned early on to avoid singing or debating touchy topics.
I gather that in certain areas & groups it is hard to remain neutral...
