Some folks, like me, don't remember things well, but I do remember a thread about this previously.

I use cheat sheets, sometimes more than other times, but if I'm singing, or playing solo, I keep them as discrete as possible. I dislike the music-stand-up-in-the-face approach as both audience member and performer, but I don't mind the stand out of the line of sight. If I'm playing back-up for someone else, I still keep the stand low and/or to the side a bit. For tunes I have memorized I simply don't refer to the stand. Usually only reminders are required anyway, so constant staring at the music isn't necessary.

If I have the djembe with me it doubles as a music stand.

I heartily dislike scripted stage patter and have heard it often at festivals and concerts. It doesn't take a genius to work in some variety, spontaneity, and off the cuff adaptation to the moment. However, it wouldn't by itself turn me off a performer unless it was excessive.

Peace, Mooh.
