I am one of those stubborn old guys that refuses to use a cheat sheet (no judgement here). I challenge myself to learn songs with lots of lyrics to keep my memory in shape.
Big Iron - Marty Robbins
Gentle On My Mind - John Hartford
You're Going to make Me Lonely When You Go - Bob Dylan
Tennesee Plates & Buffalo River Home - John Hiatt
Hotel California - Eagles
I Am The Walrus - Beatles
Man of Constant Sorrow
City of New Orleans
You? Any ideas?
