I understand totally about the classical training. My first guitar teacher was Mr Patrick: Sit up straight, thumb in the middle or the neck, fingers arched over the fret board to the point of hand cramps. Not exactly what a 10 year old, who was still reeling from hearing the Beatles on TV for the first time, was looking for.
Second teacher was Dave Barron, a NYC blues/jazz player. He's the reason I kept on paying and still do. He would sometimes let me, a kid who had a hard time remembering the difference between an Am and a Cmaj, play his D'Angelico during lessons! I was hooked for life. If my family hadn't moved, I'd be a much better player today.
Sorry I misunderstood your intentions. Didn't occur to me that the play and poster might not be one and the same. Gotta go re-watch my Fawlty Towers DVD!
