When I played in bands I had to use chord charts to get me through a set. I just don't retain that info.
I had to rerecord an old song of mine last year & spent days looking for a chord chart because, despite playing in a hundred time, I couldn't remember the chord progression. My ear isn't good enough to pick it out exactly & I didn't want an approximate - I wanted the diminishedsubcataneousnodalmodalrootstalkof the stemcell.
