Your device would have to be equipt with an FM reciever. If you had an app that would stream audio from that station it still wouldnt be reading the short range FM transmitter from the theatre
Getting a radio seems like your best option. You could possibly get a nice one at the silver moon weekend flea market.
Alternatively you would need an app that broadcasted the local fm channel. Then it would work. But seems easier to use fm device
