You just don't understand it or appreciate the genre.
[the Wiki thing]
According to Parton, the song was inspired by a red-headed bank clerk who flirted with her husband Carl Dean at his local bank branch around the time they were newly married. In an interview, she also revealed that Jolene's name and appearance are based on that of a young fan who came on stage for her autograph.
The song became Parton's second solo number-one single on the country charts after being released as a single in late 1973 (prior to the album's release). It reached the top position in February 1974; it was also a moderate pop hit for her and a minor adult contemporary chart entry. As of November 2016, the song had sold 733,000 digital copies in the US since it became available for digital download.
Here is one of the many covers that have been made of that song.
Yup they played that, and morphed the 3 versions into one song. It was smooth transition between each version, though the original is my favorite. I was told that the full concert video should be edited and posted on YouTube at some point.
You said it was gay - which I took as a dislike or "why did they make this shit" commentary. Obviously anyone could plead "don't steal my man from me" - in the original it was a woman.
More sad is a personal take, just like gay. Country music of that sort has strong roots to Scottish and Irish songs about death and the other bad shit of life. And often they were quite spirited in tempo - basically to tell life and death to fuck off. Like a good wake.
I'm not on about anything - maybe I should have said "you don't appear to appreciate or understand the genre, as it stood at the time."
*I was the one who posted the White Stripes version - I wouldn't have posted it if I didn't like it.
