OK! Haruo, Ya know, my spell checker insists that all the words I hyphenate should be unhyphenated. I actually wrote that hyphenation unhyphenated and then changed my mind. Back in the dim recesses of my mind I think I recall Miss Ooley (my high school English teacher) explaining when we hyphenate and when we don't. The information didn't "take".
Any way, I think editing is appropriate unless you enjoy getting in someone's face. I guess doing so is considered "cool" by some performers, it certainly seems there are many who enjoy offending. I always believed that one's audience was there for some better purpose than insult and hurt. It isn't a case of being boldly non PC when what you do, say, or sing hurts someone.
Of course I come from an era where being kinder and gentler was considered appropriate at all times. There is a benefit from this to the performer as well. Not only will your audience like hearing you, when it is NECESSARY to make a strong point, which might prove offensive but truly needs to be made, the contrast will be greater and there will be a greater impact as a result.
I recall that the first time I performed Ralph Chapin's poem "The Red Feast", which I set to music, the sentiment expressed in his graphic language hit home strongly and I actually got cheered!
If you don't know this poem, seek The Little Red Songbook.
