These are the chords that Dave Van Ronk made up for House Of The Rising Sun, also used by Bob Dylan and The Animals.

There (Am) is a (C) house in (D) New Or(F)leans
They (Am) call the (C) Rising (E) Sun (E7)
And it's (Am) been the (C) ruin of (D) many a poor (F) girl (boy?)
And (Am) me, oh (E) God, I'm (Am) one. (E7)

These are the chords used by Josh White, Joan Baez

There (Am) is a (C) house in (E) New Or(Am)leans
They call the (C) Rising (E) Sun (E7)
And it's (Am) been the (C) ruin of (E) many a poor (Am) girl
And (Am) me, oh (E) God, I'm (Am) one. (E7)

I learned it from a Josh White album before I heard Dylan or The Animals and prefer the White/Baez changes. I heard that Eric Burdon didn't feel comfortable singing "many a poor girl", so he changed it, though Van Ronk, Dylan and Josh White and many other male singers sang from the woman's point of view. As someone mentioned above, changing the song from a woman trapped in a life of prostitution to a man trapped in a life of paying for sex makes the song less effective. (to me at least)
