Campfire: I have two versions. The Andy M. Stewart version from his "Donegal Rain" version goes something like this.....First Line A-------D------A Second Line D------A----E7----A Third Line A----F#M----D----A Fourth Line D------A----E7-----A

After playing along the rest goes through in similar fashio. At least you've got a start. Transposition might be in line for your vocal range. Hope I could help.....
