I wish all of this internet and computer technology had been available when I was a teenager back in the 70’s!
Back in the late 70's I use to have to work the needle up and down to play each phrase over and over again until I got it - in the 80's (when I played music for a living) I used a small tape player. I hear you - you would think we would be turning out musical geniuses one after another these days!
