I was working on this one before Recovering Bassist suggested I do "I'm Gonna Kill You." That song was probably a better choice, being much shorter and more to the point.
Back in the late 1990s, there was a Disney Channel show called So Weird. It starred Cara DeLizia, who played a 14-year-old girl who traveled the country with her family and kept running into all kinds of strange, paranormal goings-on wherever she went. Sort of an X-Files for kids. Her mother, played by Mackenzie Phillips, was the lead singer of a band, and they all lived in a big RV and went wherever they could get paid to play. So anyway, there was one episode where this song came up for some reason, and Phillips did just a snippet of it but it was something I never forgot about.
I was able to find a lead sheet of it with these six stanzas, but the lead sheet didn't include the chords, only the melody, and the following stanzas didn't seem to fit very well with the meter of the first stanza. It was giving me all kinds of headaches trying to figure out until I finally remembered I could probably just find a recording on YouTube and listen to it. The one I found had a slightly different melody that was much easier to sing and made more sense to me, and fit better with all six stanzas.
This song seems to be about a man whose wife (Lorena) died before him, and he is looking forward to finally being with her again. It was popular during the Civil War. The version I listened to used only three stanzas, with some instrumental (fiddle) breaks, and repeated the last two lines of each stanza. I just did it straight through with all six stanzas for historical purposes (yeah, that's why).
