I think this is my third time through ‘Old Man”. The first time I made do with the basic chords: (line 1 of So Much More). The second time I got the hang of line 2 and have been playing that as part of the whole song myself at times in the last few months. I had forgotten about the existence of the line 3 variant, which I had previously decided was beyond me – but this time it seemed quite straight forward – well relatively speaking. So the process works. I know that I am slower than I would have been if I took guitar up when I was a kid, like I should have done, but at 69, I can still see progress and am also having fun encouraging my grandson to start playing.
