Since I posted the original comment Johnny J quotes, a bit of history might be in order.... though it doesn't detract from the deeper relevance of the idea.

The American group, "Bok, Trickett and Muir" many years ago..(20?) gave a concert at Gaston Hall Georgetown University - Georgetown - Washington, DC.
They were always being offered new & interesting songs, and that evening they introduced a song called "The Middle Class Life is Best of All"..(I do not remember the author, and can find no reference to it now)

Ed Trickett invited the audience to join in on the chorus, remarking: "You don't have to believe everything you sing." It was quite a catch-phrase in the area for awhile simply because it WAS a useful way to explain...if anyone asked... why one was singing Gospel songs or 'politically incorrect' chanties or unedited Civil War songs for historical accuracy.

It is always an issue how to present certain songs that may, in certain circumstances or to certain audiences, be offensive or uncomfortable, but many singers feel that, with proper disclaimers, non-PC songs can be not only 'shocking', but also educational. Gospel songs, at least in the circles where *I* sing, are usually just accepted as part of the culture, even if only a small % of the audience 'believes' them.

The best example I, personally, have is a Green Irish song called "One Sunday Morning", in which an Orangeman is subjected to horrendous treatment..in only 3 verses. I have know it for 45 years, but sung it only 15 or so times... and always to make a point of how hate and narrow religious attitudes can do strange things to men's 'souls'.
   I also do "The Ould Orange Flute" at times... but that never seems quite as 'pointed'.

As to "the middle class life"....I dunno... I'd like to try rich upper-class, then I'll let you know.
