I have seen a few other chords for this but they have been incorrect - lots of Bm notation (listen to the song and it is clearly a B7) - the only other one was in a different key. This is 100% correct and in the key of A, as taken from his Unearthed compilation album.

De^Alia, oh, De^Dlia Del^Aia all m^A7y life If I ^Dhadn't have shot poor Delia

I'd have ^B7had her for my w^Eife Delia's g^Aone, on^De more r^Aound D^Eelia's gon^Ae

I ^Awent up to ^DMemphis ^AAnd I met Delia ^A7there Fo^Dund her in her parlor

And I t^B7ied to her c^Ehair Delia's g^Aone, one^D more rou^And Del^Eia's g^Aone

She was low down an^Dd trifling An^Ad she was cold and ^A7mean

Kind^D of evil make me want to G^B7rab my sub mac^Ehine Delia's g^Aone, one m^Dore ro^Aund Deli^Ea's go^Ane

First time I s^Dhot her I s^Ahot her in the ^A7side Ha^Drd to watch her suffer

^B7But with the second shot s^Ehe died Deli^Aa's gone, on^De more^A round ^EDelia's^A gone

But jai^Aler, oh, ^Djailer ^Ajailer, I can't^A7 sleep 'Cause^D all around my bedside

I hear the^B7 patter of Delia's^E feet Delia's ^Agone, one^D more rou^And Del^Eia's g^Aone

So if you woman's d^Devilish ^AYou can let her r^A7un

Or you ^Dcan bring her down and do her ^B7Like Delia got ^Edone

^ADelia's go^Dne, one m^Aore ro^Eund De^Alia's go^Dne
