"It's all Gladys' fault! She's sending me straight to hell!"

Millie Jackson sounded too much like Gladys Knight and needed to distinguish herself.

Jackson's first hit song, a 1973 cover of "(If Loving You Is Wrong) I Don't Want to be Right," caused a furor. In the middle of the song, Jackson starts talking about being the "other woman" in a relationship, and loving it. The protests put her on the path to stardom, but they also created a niche Jackson has found hard to escape.

I heard the Luther Ingram version of this song the other day and — even without a spoken-word interval — I got the feeling this is a terribly dangerous song. It must have gotten an awful lot of people into trouble over the years.
