Once upon a time, I turned pages for Jamie when he performed the Kreutzer Sonata at a studio class. This was before I played it myself, so I was unfamiliar with the theme & variations movement. There's one particular variation which is 2 straight pages of 16th notes, and 2 repeats. I made the mistake of glancing away from the page for a second, and discovered to my horror when I looked back that I couldn't remember a) where we were, and b) whether we had done the repeats. I ended up half-standing & hovering for what seemed like an eternity, with Jamie kindly giving me subtle no shakes and finally a clear yes nod.Then there was the time that I turned for a friend playing in a vocal recital @ Scotiafest. He asked me at the last minute as a favour, so I accepted, forgetting that I was battling the remnants of a nasty cough. There's nothing like being on stage and NOT BEING ALLOWED TO COUGH that will make you want to cough up a lung. I managed to get through the entire thing without once coughing during a piece, but then had a friend in the audience comment on the odd expression on my face at various times.
