At 76, as much as I fight it, I have to admit I'm getting older. In particular I am gradually loosing my eyesight. For years I have used cheat sheets with lyrics and chords on 5 x 8 index cards. I no longer can see them, even with glasses. I'm realizing I need to memorize the tunes I do. Never have done that in the past as the cards allowed me to maintain a huge play list. Now of course that has changed and this old dog is going to have to learn new tricks. Any suggestions on best way to memorize tunes would be most appreciated.
