Bill,
Thanks, I didn't know that about the song. I wasn't thinking who'd be offended in 1863, but about 1966, when, at least in Florida, where I was living then, the tune was popular all over the radio, but without words.
I was living in Florida at that time, and I sometimes had a wild fantasy of writing an angry letter to the radio station: '"Doodletown Pipers" indeed. Don't you know what Mr. Doodle's first name is? Next thing you'll give us a trumpet solo of "Marching Through Georgia" & call it "Blue Bugle".' I do think people (just about everybody) in the 1960's would indeed have been more displeased by those words than anybody in the 1860's would have been.
BTW, the DT database is working again, & I found it under "Kingdom Comin" or just "Jubilo". Heavier "dialect" misspellings than I ever saw before.
