There are plenty of people who can sight read pretty much anything you put in front of them. There is an old joke about how to make a guitarist stop playing, put the sheet music in front of him! Like anything it is a learned skill for most people. Requires practice, a metronome and music to read.

The cruise ship bands are pretty good at it. They have to get music in the afternoon sometimes for a visiting act, rehearse it once or twice and perform it that night on the stage.

My wife asked if I had seen the dog bowl. I told her I didn't even know he could.
