Pure and simple... Martin Miller and Andy Timmon's "Still Got The Blues (Gary Moore Cover) - Live In Studio. I am absolutely obsessed with the quality of play by those musicians. Then; i ran across Griff's "Circle of 4th Changes" covering that song on You tube. Wrote down the finger/fret/string to the 13 chords in that song as demonstrated by Griff. Played em' on my accoustic and knew right then and there that my days of flitting across one You tube video after another were over. Bought BGU, ABGU and an electric almost immediately. I'm retired, a former musician (drums) and have a new leash on life. I want to go beyond porch-playing and feel that with time and these programs, i got a decent shot at doing so. Thank you Mr. Hamlin.
