Old Folkies Never Die! They just go out of tune.
That's my philosophy, having come of age during the Folk Scare of the early 1960's, I just never gave it up.
I started by learning Classical Guitar and think of the acoustic guitar as another voice. I love it when someone say "you really know how to make the guitar sing!
I'm not a songwriter though so I'm always on the lookout for something new and good!
