No, Matt ~ he doesn't delight, but regrets him: perhaps because he was a tolerable master, and his death would have meant the break up of the estate and his thus becoming liable to being sold to another master who might not be so reasonable?

There are so many attitudes to the American Civil War [as it is generally known over here in my experience] - from The Blue & The Gray to The Red Badge Of Courage to D.W. Griffith's unspeakably loathsome The Birth Of A Nation, a 'revered landmark of early cinema' which actually relates how the KKK saved the South when the Nigras were getting uppity after the North's victory! - that it's hard, especially to ousiders like us, to judge what attitudes to the conflict and its aftermath would be appropriate at this time of day. But, as to singing songs, that must surely depend on the song, its attitude, and several other such variables and imponderables?
