My perspective is a bit different.

I know a few thousand songs including shows and opera roles. If I learned something before April 2009, chances are very good that I still have it memorized. There are Broadway shows, operettas and operas that I can still conduct from memory.

Unfortunately, I had a major stroke that month that crippled my left side and have not been able to memorise a song since. I did not lose my ability to sight read on the few instruments I can play one-handed. Likewise, my abilities to sight-sing and conduct from a score are undiminished. I wish that I could say the same about my stamina.

I use a 12.9" iPad Pro for live performance. I can turn pages with my good foot freeing up my good arm for everything else.
