As far as I can tell the chords are along the lines of "I'm a man of constant sorrow...": Bm - E - A - F#m - G - D - F#m Bm - E - A - F#m - G - D
Verse: Bm - A - F#m - E - F#m - C - D [last time with extra C]
"Your friends say...": G - D - A - Em G - D - A - Em e f# [sixth string] G
Well its along those lines anyway, I'm sure you'll figure it out from that (or correct it) I'll write it up properly sometime, if no-one else wants to do it first. I love this song!
