Well, I am currently involved with helping book acts for a little folk festival and I can inform people who want a booking that I am not interested in looking at music stands, especially those black ones with holes in. I will make the usual exceptions for(a) people at singarounds who have genuine medical memory problems,(b) people who have just written a (good) topical song (c) people in big swing bands with those stands with fancy little hanging down flags and (d) members of the Copper family. Anybody else can learn their songs.
This infestation of stands is creeping into all music, even rock bands and such.Can you imagine the Stones or the Beatles going wild on stage behind rows of music stands?
On a separate note, if we book that Beyonce I expect her not only to learn her songs, but actually sing them.
