Hi, great message. I've been building mine for almost 45 years. I have to put them all in a cheat sheet book though. I find it hard to remember all these songs. Once I figure out "how does that go again", I'll usually remember it. I still need to keep tabs on my music.
The other repertoire I keep are the songs that I play when someone finds out I play and say "hey, play us something". When younger I would play parts of songs, but, had to start doing simplified versions of complete songs. Especially around the campfire etc. Everyone knows how to sing "We Are The Champions" right?
Keep track of your life's work, on paper. Tapes, cd's, and other elctronic media can be damaged.
