Never used a stand back when I gigged... I think it looks very amateurish. Maybe it depends on what kind of band you're in. Rock 'n roll band? No way.
If I can't remember the song(s), then I shouldn't be playin' 'em. I missed a note or chord here or there, but I always knew the basic structure of the song.
"I feel sorry for people who don't drink. When they wake up in the morning, that's as good as they're going to feel all day." -Frank Sinatra
