You and Bobby Howe and JD Jarrell will become very familiar with their choices they have. Elvis, B.B. King, Johnny Cash and others are in the songs list. Not to mention that you will find instructors to teach you the actual play styles of other names.
I've got arthritis in my hands bad and use the guitar to help keep them working as well.. you won't find very many things that will help you keep your mind, ears, eyes and hands all busy.. not to mention the tongue as you bite it as you get frustrated in the beginning of the learning... I don't claim to be an expert by any means.. but I will stand behind these folks here and help boost them as they've boosted me with all they've given me!
