My ID expired and I have a temporary paper one. Is this valid?

Sort of. You must bring the official paper temporary ID as well as your expired ID. If you lost your ID and only have a temporary paper one, you will not be admitted to a 21+ show or allowed at the bar for an all-ages show. If you are bringing a temporary paper ID and your expired ID, the paper one must have the correct dates and the photo must be a like-resemblance.
