I don't think you are but not 100% you aren't being sarcastic. I spend a lot of time in Nashville & the worst working musicians there are better than most. The good ones are mind blowing! If you're a live jukebox what's wrong with looking at the chords just to get an idea? Most of us have learned thousands of songs if someone yells out a Journey song or whatever, yeah I learned all that stuff but I haven't played most of it in 20 years I think most would need at least a quick look. I certainly would.
