An app that helps ailing celebrities find a stand-in in a crisis

There a lot of celebrities who are in worse heath now and likely to have to cancel for projects after they've gotten a solid yes from them. (hello, Ozzy in the upcoming Black Sabbath tour in the UK!)<br><br>I think someone should develop an app where you can see all celebrities who are available (or their assistants are) and ready to step in in an emergency. <br><br>Make it so that you can search by category: Singers, actors, dancers, comedians etc. <br><br>Make it so you can also filter by the ailing celebrity's style (like, you can't think of another Ozzy singing Paranoid with Black Sabbath). <br><br>And also by location, because you can't transport a stand-in from the other side of the world. <br><br>And by availability and price obviously.
