This is a quick to set up "booth" as it were, intended as a privacy shelter for camping....

No I mean something like a vertical tent to allow people to change costume during a show (Spider flex?)

I have a portable tent that pops up in a vertical position. I use this when I am in garden parties. I think this type of tent is used as a changing booth in beaches. I bought it for about US$15 at a sale. Try searching for "beach tents".

I got mine at K-Mart- a camp shower tent it was called. They are on sale this tgime of year as they close out their camp stuff to make room for "Back to School."

I mean a back drop ( this could be the real name of this stuff in english)
