Most of them I play from memory and some that people request if I do not already know it than Ican bring up on my ipad but it is rare that I have to use it or sheet music. When I do a concert I know all the ones I will play.
That's very impressive - my memory is shocking these days and I always rely on my iPad for the chord sequences, which is bad because then you don't memorize it and it's a bit of a vicious circle.
I have done concerts from over 10,000 to as few as 16
I always found the concert for fewer people were more nerve wracking than the bigger ones, as it was a more intimate relationship with the listeners - although I've never played to 10,000 - I think maybe 2,000 or 3,000 was my biggest audience at a local music festival.
I practice for 3 hours most days so knowing them is from that.
I'm lucky if I get three hours a week!! I get jealous every time you mention that 
Thanks for sharing some info about your life - it's fascinating to hear someone who has done so much ...
Cheers
