This is a great thread, Mike! I love hearing about people's histories and what they're doing with music these days. Here's my story:
My father played guitar and built his own pickup and amp back in the 1940s. He played barn dances: Hank Williams, Jimmie Rodgers (singing brakeman), and other country stuff of the time. My old man could yodel to shake the house. He gave me a Silvertone cheese cutter for my 10th birthday and tried to teach me, but one of his fretting fingers had been cut off, so the bass runs just wouldn't work. I later took up finger style on a classical guitar, learning from the folk guitarists around town.
After college (English) I took theory from the West Bank School of Music, Minneapolis. That lead to a duo act with a harmonica player. We taught each other and did old timey country blues. He later went on to electric guitar, and I stuck with acoustic--did solo gigs, guitar/harp/shouting (a little like singing). Kept semi-pro for about five years. Put it up for about another eight years--and then I met Lydia, my sigoth.
Lydia is a pianist, classically trained, and a folk music (from all over) afficiando. She wanted me to pick up the guitar again. I played what I could remember, and she said, "No, you only have licks! You need beginnings, middles, endings, and maybe parts!" Well, I knew all that was left was a handfull of licks. Geez, don't be so hard on a guy!
So, I got myself some classical repertoire and started that study. That was about nine years ago. Since then, I've learned more on arranging my own stuff from sheet, got the ear back, and do a sort of classical/folk fingerstyle hybred. Oh yeah, slide style has always been part of all this with open tunings like D and C. Jazz techniques have entered in. I have no idea what to call this style--mutt?
We were doing some Christmas carol duets for the family this past season, and someone commented on my "Jimmie Hendrix" fills. Oh, gee, sorry. Guess I was bending it a little on "Oh Come All Ye Faithful!"

And then there's the rhythmic slants on "What Child Is This," but that's because I learned it as "Greensleaves" way back when. Sorry. To me it is a secular love song, you know, like it originally was? Lydia was laughing and broke into some "Bumble Boogie," just out of spite I guess.
About five years ago, Lydia and I were browsing around the Folk Arts music shop in downtown Colorado Springs. They had a reissue National Steel on hand, so I played that a while. Lydia liked the sound, so she bought it for me.
Huh. Gee, hey, let me try out that jumbo Martin over there! She said no. Emphatically. So the National Steel is my main box, a cheap Dean electric/acoustic koa wood comes in next, and then a relatively cheap Epiphone Sheridan for straight-up 30s/40s jazz work. Amplificaton through mics, PA, Crate acoustic amp, or Dean Markley electric amp.
Guitar heroes: Pat Donahue (listen to A Prairie Home Companion--he's the top dog guitar man now), T-Bone Walker, Brownie McGhee, Hendrix, Reinhart, Pass, Segovia, and on and on. And then there's my father who told me that no matter what I play, play from the heart. If it's not exactly like the record, screw it and keep doing it your way. Make the tune your tune.
Lydia disagrees, of course. "Sheets of sound," she exclaims! "Back to the melody, jerk!" Well, yah, I see her point--get it on back home. I'm no Coltraine, that's for sure!
But I still maintain that the way I do the melody for "Goodnight Irene" is the way Leadbelly did it--she knows the more modern, softened version. So THERE, Lydia

What a pair we make.
I love almost any kind of music, eventually, after I get acclimated to it.
